CAPTURE® Version History
When saving a graph picture, it is now possible to choose from between three preset image sizes: Small (800 x 600 pixels), Large (1600 x 1200 pixels), and Graph Window Size. Large graph images use a default label scale of 2x for added clarity.
Humidity Correction, Forced SNIFF Mode, and BA Spill Correction may now be applied to the built-in sample RAD7 data files.
Humidity Correction may now be applied to RAD H2O radon in water data. In the previous version Humidity Correction only had an effect if the Radon Measurement Method was set to Radon In Air, RAD AQUA, or Water Probe.
When viewing RAD H2O radon in water data, the Radon In Air graph line is no longer visible. Corresponding Radon In Air statistics are also hidden.
When a new version of CAPTURE is available, the latest changes to the program are now listed in the Update Available Dialog.
When exporting column-based RAD7 data to a text file or to the clipboard, entries in the Units Byte column are no longer followed by a premature line ending. Data will now be formatted properly when viewed in a spreadsheet application.
An alert icon now appears if a RAD7's clock is set to the wrong time of day. Previously the alert only appeared if the RAD7's clock was set to the wrong day entirely.
When Chart Recorder data has been obtained but is found to contain problems that prevent it from being displayed, an explanatory message now appears along with a button for viewing a detailed list of errors in the data set.
The Graph Statistics Panel now devotes more space to any warning messages related to the data point nearest to the mouse cursor.
CAPTURE now checks for updates more successfully over slow Internet connections.
Version 5.5.4 (February 2017):
The Meaningful Thoron Threshold is no longer reported as zero for any records with no thoron counts. This resolves a bug that was introduced in version 5.5.3.
RAD7 data files containing records from prior to the year 2000 are now interpreted properly.
The program no longer has problems parsing certain figures expressed using scientific notation.
The RADLINK disabling procedure now works properly on RAD7s with a variety of different firmware versions.
The online CAPTURE Help is now stored in a different location for each version of CAPTURE.
CAPTURE Version 5.5.4 is intended to be the final Windows XP compatible version, and in the future it will be offered in a standalone edition as an option, without automatic updates.
The program is no longer likely to crash when the application error dialog box appears and the Do Not Show This Message In The Future button is clicked. After clicking this button, redundant error messages will no longer be recorded in the Program Log File, preventing disk space from being wasted.
When the program reports that a data file does not contain any valid records and the user clicks the Show Details button, a program error no longer occurs. Instead a window appears listing each problem with the data set. A maximum of 1000 items appear in this list, even if the data file is afflicted with more than 1000 problems.
The program now evaluates large data files and determines whether they can be parsed more quickly, particularly if the file name extension is known to be unsupported, for example if it is a .JPG or .DOCX file.
When right-clicking on a graph display or Chart Recorder surface for the first time, all of the available contextual menu items are now enabled. Previously it was necessary to right-click twice before certain commands became enabled.
When configuring Run Parameters, relevant error messages are now displayed in a streamlined version of the Error Message Dialog. For example if the Radon Measurement Method is set to Big Bottle System and the data was recorded in a protocol that is not compatible with that system, an alert message will appear explaining the problem.
It is now possible to select multiple RAD7 data files using the Open dialog box when graphing and combining data.
The Export Cleaned Up Data button is now enabled in the Error Message Dialog only if one or more data records were unable to be parsed.
When humidity correction is enabled on a graph, the Meaningful Thoron Threshold is now affected to the same degree as the thoron concentration.
The average Relative Humidity of a selection is now reported in the Graph Statistics panel even if the Relative Humidity graph line is hidden.
The Statistics panel now displays a "File Created By" label plus the name and version number of the program used to create the data file. This replaces the "CAPTURE Version" label and a corresponding version number. This allows the program to indicate when a data file was created using a different software program.
The CAPTURE documentation is now available exclusively via the Durridge website, ensuring that the Show CAPTURE Help menu command works reliably on macOS.
If the application is closed immediately after launching, it no longer records an empty preferences file to disk.
It is no longer possible to rename a RAD7 or DRYSTIK that was added manually until after a connection has been established, because doing so caused the program to crash. For the same reason it is no longer possible to connect to a RAD7 or DRYSTIK until a serial port has been selected.
The Combine RAD7 Data Files window now supports drag and drop. RAD7 data files or entire folders full of data files may be dragged into the window's list box and combined.
The system for creating Run Summary Reports has been redesigned, resulting in improved report formatting and improved handling of situations that previously produced errors.
If a record in a RAD7 data file is found to contain parameters that are inconsistent with the parameters of the other records in the same run, the problem is resolved and the user is alerted.
CAPTURE application log files and Chart Recorder log files are now stored in \Users\UserName\AppData\Roaming\ on Windows, and in /Users/UserName/Library/Application Support on the Mac. The application log files are now organized into folders by year. A different log file is created for each day the program is in use. Previously a separate file was established for each session. Files now contain more extensive headers. Log files older than one month are no longer purged.
CAPTURE now checks to see whether a data file has an invalid file name extension before attempting to open it. This prevents the program from stalling while attempting to parse large unsupported files such as Photoshop images or PowerPoint documents.
A menu command has been added for showing the CAPTURE program logs.
The CAPTURE Preferences file is now titled Durridge CAPTURE Preferences.txt. Previously this file was titled CAPTURE.ini.
The formula for determining which graph points to connect with line segments now produces better results when run numbers are out of chronological order.
When initiating a manual RAD7 data download operation, CAPTURE now times out after 60 seconds. Previously there was a 30 second limit before timeout.
Exported Run Summaries files that are formatted using comma delineation now use the .csv file name extension. This makes it easier to open them directly in spreadsheet programs.
CB Spill Factor values may now be obtained from the RAD7 if the device has the latest version of RADLINK installed. In these cases is no longer necessary to manually specify the RAD7's calibrated CB Spill Factor value in the Preferences Window's RAD7 Profiles Editor. If this value is entered manually, it may be either "locked", preventing it from being overruled by information obtained from the RAD7, or left "unlocked", allowing it to be overruled in cases where such information is able to be obtained from the device.
CAPTURE now supports Temperature Data Files in which the year, month, and day values of date expressions are separated by dash characters. Previously only slash characters were supported as year, month, and day separators, and this created compatibility problems with more recent versions of the EasyLog USB software.
A new built-in Temperature Data Profile labeled "Lascar EasyLog USB YMD" has been established to accommodate the latest Lascar EasyLog USB data format, in which dates are expressed in the Year-Month-Day format. Earlier versions of the Lascar software are supported by the existing "Lascar EasyLog USB DMY" profile.
Built-in Temperature Data Profiles may no longer be edited or removed. When CAPTURE launches, any built-in profiles that were previously deleted will be restored automatically.
A new Tools Menu command can be used to shift the dates of a Temperature Data File and then re-save the file in any of CAPTURE's built-in temperature data formats.
Temperature Data Files expressing times using a 12-hour clock format are now parsed successfully. Previously times between 12:00 AM and 1:00 AM were interpreted as occurring between 12:00 PM and 1:00 PM.
Exported RAD7 printer output now contains accurate temperature values when expressed in the Fahrenheit unit.
When necessary, thoron sensitivities are now calculated by analyzing the content of RAD7 printer output data. This is only possible when the Thoron option is enabled in the Setup menu.
When thoron concentrations are calculated based on estimated RAD7 sensitivity values, a notification now appears, along with recommendations on how to achieve more accurate thoron readings.
Sensitivities derived from RAD7 Profiles are now identified as such in the Graph Statistics Panel.
If a RAD7's humidity sensor is faulty, humidity readings are now reported as "[Unknown]" in the Graph Statistics panel.
CAPTURE's built-in sample RAD7 data files may now be opened using a command in the File menu. Water temperature data will be made available for each sample data set automatically when the Run Parameters Dialog is opened and the Radon Measurement Method is set to a radon in water accessory such as the RAD AQUA.
When opening a graph, the Radon Measurement Method is now automatically set to RAD H2O for any runs that are found to have been recorded in WAT mode.
Separate Radon in Air and Radon in Water graph lines may now be viewed for RAD H2O data. The Radon in Air concentrations are calculated based on the RAD7's known or assumed SNIFF sensitivity, while the Radon in Water graph line remains based on the pre-computed concentration figures provided by the RAD7.
Radon in Water graph lines now appear automatically if Radon in Water data is present, even if the Radon in Water checkbox was unchecked during the previous session. This is intended to prevent users from mistaking Radon in Air graph data for Radon in Water data.
When Chart Recorder data is logged to disk, it is now saved in either the R7CDT format or the R7RAW format, based on the user's choice. Previously R7CDT data could only be saved if R7RAW data was being saved as well, but this is approach is no longer necessary as a means of preserving the RAD7's raw data output because the raw data content is present within the R7CDT file.
When a Graph Window opens, the top panel of the window now immediately displays the average concentration of the radon in the data set. It no longer contains a prompt asking the user to specify the Radon Measurement Method.
Radon data parameters may now be applied on a per-run basis, rather than being applied to an entire data set, and therefore the Graph Parameters Dialog is now known as the Run Parameters Dialog. An individual run may be selected and assigned a Radon Measurement Method of either Radon In Air, RAD AQUA, RAD H2O, Water Probe, or Big Bottle System. Clickable labels now appear over each run on the graph, providing easy access to the controls for editing the corresponding Run Parameters.
RAD7 sensitivities are now obtained using the Special GetCal command, which is supported in newer versions of RADLINK. These sensitivities are saved in the RAD7 data file and allow for the precise determination of radon and thoron concentrations. When these sensitivities are not able to be retrieved, CAPTURE calculates them by analyzing other information within the file.
RAD7 Device Data and configuration information is now stored on a per-record basis, rather than a per-file basis. This makes it possible for CAPTURE to retain device information during Export and Combine operations.
If CAPTURE detects that a RAD7 is configured to express concentration values using incompatible concentrations units (CPM or Total Counts), the user is now prompted to switch the RAD7 to a compatible unit before downloading data. Additionally, the RAD7 Units Setup dialog box no longer permits the user to select an incompatible concentration unit type.
If a RAD7 data file contains concentration values stored in an incompatible unit type and the RAD7's sensitivity figures are unknown, the user is prompted to specify these sensitivity figures so that concentration values can be calculated. Once this calculation has been done, the data file can then be saved and subsequently reopened without incident.
RADLINK may now be installed and removed using the RADLINK Operations command, which is available in the Tools menu. RADLINK versions 253, 301, and 311 are supported. This feature allows users to restore RADLINK if it has been lost, and to upgrade a RAD7 to a newer version of RADLINK, which is required to obtain comprehensive device sensitivity data.
The Tools Menu now contains an option for shifting the content of a RAD7 Data File by a certain time interval. Each data record's time stamp is shifted forwards or backwards by a specified amount. The modified RAD7 record set is exported as a new RAD7 Data File.
The Tools Menu now contains a Concentration Unit Converter and a Sensitivity Unit Converter. These are used to convert user-supplied concentration and sensitivity values between four available units: Bq/L, Bq/m3, dpm/L, and pCi/L.
In the Chart Recorder, when viewing data from a RAD7 Group consisting of multiple RAD7s, the devices must now be synchronized to within one quarter of their common Cycle Time in order for their respective data points to be combined and averaged.
If a RAD7's clock is incorrect, the right edge of the timeline on the Chart Recorder will now show the RAD7's reported date and time, rather than the current actual date and time. This prevents the lines extending from the most recent data points to the pen tips from advancing in the wrong direction.
The total number of counts associated with the data point nearest to the cursor is now reported in the Graph Statistics panel.
The Graph Statistics panel now displays an alert icon next to the RAD7 calibration date if the RAD7 had not been calibrated within one year of the measurement. Similarly an alert icon appears if RADLINK needs to be updated or if the RAD7's date and time settings are incorrect.
Shaded regions indicating excessive High Voltage Duty Cycle readings now start at the beginning of the affected cycle, rather than at the end of the preceding cycle. This prevents large shaded regions from appearing between runs, except where appropriate.
Clicking the Forced SNIFF Mode, Correct For Humidity, or Correct For B to A Spill checkbox now causes the highlighted selection average and Slope Line to automatically snap to the appropriate position.
When thoron uncertainty values are unknown, the data is now written to disk using the proper notation format, preventing information from being lost.
If the Check for Updates option is disabled in the Preferences window, CAPTURE will no longer display a warning message when Internet access is unavailable.
In the Run Configurations Dialog, the specified Temperature Delay is now applied only if the Water Temperature Data Source is set to Temperature Data File.
The formatting of printed graphs including statistics has been improved, particularly for graphs printed in a landscape orientation.
Machine-generated foreign language translations have been removed from CAPTURE. Grammatically correct English content will appear instead. It is no longer possible to use the program's Preferences Window to specify whether to enable foreign language translations. If the system is configured to display Chinese characters, these will appear as they did previously, since they have been translated by hand.
RAD7 Data files may now include Special SprOn and Special SprOff responses in addition to the expected content. These portions are stripped out during parsing. This allows CAPTURE to read data files assembled outside of CAPTURE using typical serial port output.
The macOS version of CAPTURE is now code-signed, so computers with default Gatekeeper security settings will no longer refuse to launch the application.
The appearance of printed graph images has been improved. The graph is now displayed at a higher resolution and labels are rendered in a larger font for improved readability. The statistics that appear under the printed graph image now include information on the Selection Slope Line, Radon in Water, Thoron, and Thoron in Water, but only if the associated lines are are present on the graph image.
The system for rendering the graph legend has been optimized, resulting in significant performance gains, particularly on Windows, and particularly when multiple graph lines are visible.
The graph's grid line spacing now changes at more frequent and regular intervals as the graph is zoomed in and out, ensuring that a reasonable number of background grid lines appear at all zoom ratios.
The placement of graph elements, including axes, legends, and labels has been improved, particularly when the graph image is rendered using a nonstandard scale factor, as when printing or saving the image to disk.
When the Radon Measurement Method for a data set is set to Radon in Air, the Radon in Air graph line is now made visible, and the Radon in Water graph line is now disabled.
If a value of one million or greater appears in a text field in the Graph Controls Window, it will use the letter M to represent Millions. Previously such non-numeric characters were ignored when parsing user-supplied values. Now this type of notation is interpreted correctly.
Custom graph concentration scales may now be set to no higher than 100 million units, and no lower than -100 million units. This applies to the Radon, Thoron, Temperature and Humidity graph scales.
When user-specified numeric values are written to the program's Preferences file, the positive or negative nature of the value is now recorded properly. Previously when negative values were used to specify graph scales and water temperature offsets they were converted to positive values when saving.
If a RAD7 loses its calibration settings, CAPTURE now warns the user that the device's data is unreliable and that the RAD7 should be returned the DURRIDGE for service.
It is now possible to specify the desired graph label scale when exporting a graph image. The chosen scale dictates the minimum allowable image dimensions. The PNG file name extension is now added to the desired file name under all circumstances.
When opening a Graph Window, it now appears fully on-screen, even if the most recently viewed graph window was positioned partially off-screen.
The system for cascading multiple Graph Windows has been improved on Windows OS, with respect to each Graph Window's title bar and menu bar height.
Support for the Big Bottle System has been improved. It is now possible to select preset configurations based on Revision C of the Aerator Cap design. This applies to both the Glass Jug System and the Soda Bottle System.
The Statistics Panel now contains additional information about the RAD7 data file, including the CAPTURE version number used to download the data, the platform used (Windows or Mac OS X), and the file creation date.
On Mac OS X it is now possible to drag any file type onto the CAPTURE application icon, and the program will attempt to open it. Previously only .R7cdt, .r7raw, .cdt, and .raw files could be opened in this manner.
Administrative tools have been developed for more user-friendly thoron calibration procedures.
RAD7 Data file icons now appear at high resolution on both Mac OS X and Windows.
A Tools menu has been added to the menu bar. It provides access to new utilities such as the RAD H2O Radon In Water Calculator, and the Terminal Window. The RAD H2O Radon In Water Calculator computes Radon In Water concentrations based on user-supplied Radon In Air and Water Temperature Values. The Terminal Window provides an interface for manually issuing serial commands to any device, including RAD7s and DRYSTIKs.
CAPTURE is no longer localized into German, Arabic, and Hebrew. German text did not fit well in the program's user interface (luckily the majority of German speakers are literate in English.) Arabic and Hebrew texts produced problems related to the right-to-left nature of these languages, and suffered from issues with string manipulation.
Texts in the remaining languages have been shortened where necessary to conform to the spatial requirements of the user interface. This affected Spanish, French, Italian, Norwegian, and Swedish.
The Chart Recorder zoom level is no longer reset when the RAD7 status is refreshed.
The Chart Recorder no longer becomes stuck in an endless refreshing cycle when a RAD7's runs were recorded out of chronological order.
The reliability of RADLINK related utility functions has been improved.
Downloaded R7CDT data files containing incomplete printer output data or missing RAD7 identification information are now parsed more effectively. Any RAD7 device information such as the serial number and calibration date are now retrieved if available.
When printer output data is unavailable for some records, the user is notified of the issue.
Exporting column-based text data using comma delineation produces a .csv text file which is directly compatible with Excel and other software.
The Clock Setup dialog box now allows the desired year to be entered. This dialog box is accessed from within the Chart Recorder.
The Macintosh version of CAPTURE no longer crashes when right-clicking on a graph or chart.
When a dialog box appears on Windows OS, the most commonly used button is now assigned the focus, so that it can be triggered by pressing the Enter key.
When RAD7 data is downloaded, any errors in the data are once again reported properly. These error messages are not displayed when applying changes to graph configurations. Note that previous versions of CAPTURE will be unable to open files downloaded using CAPTURE 5.4.1.
R7RAW files may now contain comments, which start with /* and end with */. These comments were previously supported only in R7CDT files.
Downloaded RAD7 data is now saved in a format that retains any data errors so that the errors can be reported and accessed during future sessions. Such errors are removed only when data is manipulated through exporting or combining operations.
The user interface for installing and removing RADLINK has been improved, and potentially problematic operations are no longer supported. CAPTURE now supports operations involving the latest version of the RAD7 firmware.
CAPTURE now displays the hardware revision number in addition to the firmware version number for DRYSTIKs running firmware version 1.2.1 or newer.
DRYSTIK Firmware can now be updated successfully. This addresses a regression that was introduced in CAPTURE version 5.3.7.
Problems have been addressed in the statistical figures that may be included when printing a graph image. These graph statistics are now visible on printouts by default.
Windows are restored to the same sizes and positions they were left in. Previously they could reappear in the wrong locations on the Windows OS, with the title bar off the top edge of the display.
When a device is detected, its icon now appears in the toolbar immediately and is automatically selected.
If a RAD7 data file is found to have been created using a newer version of CAPTURE than the one being used, the user is notified and encouraged to update CAPTURE to the latest version.
CAPTURE no longer creates RAD7 Profiles associated with the device serial number 0001.
After using the Graph Parameters Window to set the Radon Measurement Method to RAD AQUA, RAD H2O, Big Bottle System, or Water Probe, the Radon In Water graph line now automatically becomes visible.
Values written to the preferences are now expressed using higher precision, ensuring that close numbers are not treated as identical. This change resolves a problem in which the program did not differentiate between very similar dates and times.
When exporting a RAD7 data file containing combined data records, the exported records are now sorted chronologically, rather than by record ID number.
The Zoom Slider no longer produces erratic results. This addresses a problem that was introduced in CAPTURE 5.3.9.
When scrolling the graph or translating a selected region horizontally, the graph's Y axis scaling animation now runs for a particular amount of time, rather than for a particular number of frames, improving performance on slower computers.
RAD7 status refresh operations can now be safely interrupted by Download and Relay operations.
If the Main Window is suddenly closed while a RAD7 status is being refreshed, CAPTURE now cancels the status update more gracefully, informing the RAD7 that it should cease sending data.
TCP data transfers are now reported in the Log Window without visual glitches.
RAD7s are now listed in order by serial number in the toolbar and in the Log Window.
RAD7 connections are no longer as easily disrupted. When a RAD7 fails to respond correctly to a command, CAPTURE attempts to re-issue the command several times, at fixed intervals, before giving up and reporting that the connection has been lost.
Certain kinds of RAD7 records are no longer incorrectly identified as having been recorded in Thoron mode.
Terminology shown in the user interface has been changed for clarification; for example ‘Change Radon Source’ has been changed to ‘Specify Radon Measurement Method’.
Visual corruption no longer occurs on the graph after zooming in on a selection of RAD7 data, then bringing up the Graph Parameters dialog box.
CAPTURE no longer attempts to calculate the SNIFF sensitivity when the Window D counts overwhelm the Window A counts. In these situations the default SNIFF Sensitivity value is used. This in turn affects the calculated Thoron Sensitivity, which is usually set to a certain portion of the SNIFF Sensitivity.
Records recorded in Thoron Mode are now identified as such by CAPTURE. This resolves a bug introduced in Version 5.3, in which thoron mode indicators in RAD7 Data files were not properly parsed.
If a RAD7 is overdue for calibration, it's toolbar is now marked with an alert symbol. The alert symbol also appears near the Calibration Date listing in the Graph Window's Statistics Panel.
The serial I/O code has been refined to prevent multiple occurrences of commands being sent to RAD7s unnecessarily.
Toolbar icons are no longer prone to disappearing in the Windows version of CAPTURE.
Cumulative spectrum data may now be saved to a text file, using the Export Spectrum Data button in the Cumulative Spectrum Window.
The peaks in the Cumulative Spectrum Window are now rendered with greater precision.
The system for evaluating the count distributions between windows A,B,C,D, and O has been enhanced.
RAD7 software administration tools have been made more user-friendly.
The Chart Recorder new advances in real time, instead of only advancing in 5 minute intervals. (Scrolling will only be perceptible however if the cycle time is short and the chart view is fully zoomed in).
Chart Recorder data is now obtained immediately upon the completion of each cycle. This resolves a bug introduced in an earlier version of CAPTURE.
The Thoron and Thoron in Water pens are now shown on the Chart Recorder only if the RAD7 is currently in Thoron mode. Previously these pens were visible if any points already on the chart were recorded in Thoron mode.
The Chart Recorder’s Y axis scales now change dynamically based on the range of concentrations, temperatures, and humidity values within the currently visible data.
Data sets containing only one record can now be displayed on the Chart Recorder. Therefore a point now becomes visible as soon as the first cycle of a test has been completed.
The DRYSTIK status panel no longer confuses the Date of Manufacture and Lifetime Pump Usage values.
When a DRYSTIK is idle, CAPTURE now accurately reports the state of the DCC Output/Internal Pump switch. Previously the state of this switch was only properly reported while the DRYSTIK was live.
Before rebooting a DRYSTIK or updating its firmware from within CAPTURE, the device is stopped. This speeds its reboot time and prevents the program from timing out while waiting for the DRYSTIK to respond.
On small displays, the Main Window is no longer positioned with its title bar above the top edge of the screen. Resolutions as low as 1024x768 are now properly supported.
The vertical scale of the Chart Recorder now accommodates radon, thoron, temperature, and humidity readings that are still in progress, and these figures are now reported immediately when the chart appears. White space no longer appears below the horizontal axis.
RAD7 connections are no longer lost in certain situations.
The Run Selection pop-up menu no longer reverts to its previous state when making a selection.
RAD7 detection now occurs more quickly and is less processor intensive. While a scan is occurring the program remains more responsive, and the associated progress bar provides a more accurate indication of how much time is remaining.
When a RAD7 operating at 1200 baud is detected, CAPTURE now offers to increase its speed to 9600 baud instead of to 19200 baud. The associated dialog box no longer reappears unnecessarily after rescanning for RAD7s.
The Download Data From All RAD7s command now works properly.
The Main Window can now be resized to fit on smaller laptop displays.
The appearance of the Chart Recorder button panel has been improved, particularly on Windows.
CAPTURE now checks online for DRYSTIK firmware updates instead of relying on an embedded file. Going forward, outdated versions of CAPTURE will still be able to install the latest version of the DRYSTIK firmware onto ADS-3 and ADS-3R devices.
When a graph opens, the selection bars are now positioned so as to encompass all the data points.
In the Graph Window, double-clicking will zoom the view in only if a subset of the data points are selected.
Stability improvements have been implemented in the Chart Recorder.
Multiple RAD7 data sets can now be successfully combined even if they are not being saved to disk.
The Show Data File command now reveals the location of the file associated with the current graph and also selects it in the Windows Explorer or Mac OS X Finder.
Changes have been made to the Mac OS X version of CAPTURE for future deployment as a Cocoa application.
CAPTURE now remains fully responsive when RAD7 statuses are being retrieved. The revised status update procedure is considerably less CPU-intensive.
The sensitivity values displayed in the RAD7 Profile editor in the Preferences Window are now calculated based on the content of the front most graph window or chart recorder.
Upon completion of RAD7 serial operations that involve redirecting infrared printer output to the serial port, any ensuing output is now sent back to the printer. Previously CAPTURE only restored the printer operation if the RAD7 had been configured as such prior to the serial operation.
Device communication failures are now handled in an improved manner. When CAPTURE fails to receive an appropriate device response after four consecutive attempts, the connection is closed and the user is prompted to reenter the device's connection settings.
The Big Bottle System configuration interface now includes a control for selecting which DRYSTIK model is being used, if any, and the preview diagram is updated accordingly. DRYSTIKs using different NAFION tubing lengths contribute differently to the internal air volume of the overall apparatus, and this affects the calculated Radon In Water concentration values.
TCP network connections may now be monitored in the Log Window, under a new tab alongside the existing Application Log and Serial Ports tabs.
The Include Supplementary Data option has been removed. Supplementary data is now included automatically whenever a download procedure is initiated from a RAD7 capable of two-way communication.
Dial-up modem communication features have been removed due to underutilization.
Visual glitches affecting the Windows version of CAPTURE have been resolved.
CAPTURE can now more reliably communicate with RAD7s via a local area network.
RAD7 icons in the toolbar are now shown in the correct order according to serial number.
The system for reestablishing connections with existing RAD7s has been improved.
User interface elements and chart graphics in the Main Window are now refreshed as needed.
A bug has been fixed that caused raw RAD7 data to be written to disk repeatedly, creating unnecessarily large data files.
All RAD7 data lines are now included in chart recorder log files, even if they are not able to be parsed, making it easier for users to identify errors.
Several changes have been made to CAPTURE's code structure in preparation for future devices and newer compilers.
Visual glitches in the user interface have been resolved.
An issue which prevented files from being combined has been resolved.
Application stability has been improved on Windows.
Uncertainties are now calculated properly when based on the scatter of points. Previously results were too great by a factor of two.
When zooming out of graphs, CAPTURE now renders data sets without graphical glitches.
Support for RADLINK version 3.0 has been added. In this version of RADLINK, the Special ComSpec command outputs spectrum data for the entire run, rather than just the current cycle.
A Cumulative Spectrum Window has been added. It contains a histogram displaying the results of the Special ComSpec command. Support is included for RAD7s containing both RADLINK 2.5 and 3.0.
Calculations requiring knowledge of the RAD7's internal volume are now performed with greater accuracy.
RAD7 commands may now be issued manually while status updates are underway.
Minor graphical and usability enhancements have been added, such as an alert icon appearing when downloaded data is to be saved over an existing file.
The Graph Legend can now be positioned on any of the four corners of the Graph Window or Chart Recorder.
The Export Column Based Text operations now allow for the inclusion of Meaningful Thoron Threshold data for air and water.
The algorithm for computing the Meaningful Thoron Threshold has been refined.
Expressions of whole numeric values will no longer conclude with decimal points. This will make it easier for statistical analysis software programs to identify exported values as numeric content.
CAPTURE no longer issues duplicate error reports when downloading and graphing data.
Any RAD7 data that can not be parsed is no longer included in exported R7RAW or R7CDT data files. Problematic data is however saved to disk as it is being downloaded, so that it may be properly accessed.
Minor rendering problems have been resolved in the Chart Recorder display.
Reported thoron uncertainties now more closely match those values seen on the RAD7 printer output. Greater uncertainties will be seen for low thoron concentrations.
A problem involving the prohibition of thoron sensitivity values of less than 0.1 cpm/(pCi/L) has been addressed. This limit is now scaled with respect to the concentration unit used, allowing data sets whose thoron concentrations are expressed in units other than pCi/L to accept reasonable changes to the thoron sensitivity.
The C:A Count Ratio is now properly reported for selections. Previously this was reported as the average of the C:A count ratios of the selected data points. Now this value is calculated as the ratio of the sum of all C counts to the sum of all A counts comprising the selection.
Uncertainty figures are no longer offered for C:A Count Ratios, and undefined ratios in which no A counts were recorded are now reported as "∞:1".
While listening for incoming commands to relay from a remote computer to a connected RAD7, CAPTURE now disables download operations and RAD7 status updates. Previously such operations could compromise the program's responsiveness to incoming commands.
CAPTURE now does a better job of determining whether records were likely recorded in GRAB mode, and uses this information to determine whether thoron data is valid and should be visible on a graph. (Records recorded in GRAB mode contain invalid thoron data.)
Radon inspection reports may now be exported from CAPTURE. These reports are saved in HTML format and include graph images plus user-supplied information on site conditions and testing parameters. The visual content of the file is embedded directly inside the HTML. Since no separate image files are involved, the report has the benefit of portability typical of PDF files.
The Export RAD7 Data command now presents the option to include or exclude supplementary data, when such data is available. Previously it was not possible to exclude supplementary data when it was present in the file being graphed. Now that this is possible, any exported content can be made to adhere to the well documented formatting standard used by the RAD7 when it responds to Data Com or Special ComAll commands.
The calculation of radon concentration uncertainties has been improved, especially in cases where very few or no counts were recorded. These figures now match the output provided by the RAD7, even though they are calculated independently.
Records recorded in WAT40 or WAT250 modes now produce warnings when graphed using the Big Bottle System as the Radon Source.
The Big Bottle System graphics seen in the Open Data File dialog have been updated to show Durridge's new aerator design.
The logic used to calculate the minimum meaningful thoron threshold has been improved.
The Chart Recorder's Y axis now scales to accommodate the points in the selected View Range.
A bug which prevented RAD AQUA and Water Probe data from being properly loaded has been fixed. CAPTURE now displays Radon in Water data successfully.
