TQSoft now allows for a set of calculations to be repeated on sections of a test. For example, min, max and average I-Calcs can be applied separately to heat up, sterilization and cooling stages, and three calculation sheets can display results for each stage.

There is a sample test (Penetration) that illustrates this functionality. There is also a sample report Dist & Penetration that illustrates the reporting sheets.


Groups can now be used to generate separate chart, data list and position diagram for each group in reports manager.


The row calculations in the Data List are no longer restricted to temperature. If all channels are humidity, then calculations are for humidity. If a mix of channels, then first channel shown will determine the calculation type.


Rate of change I-Calc can now insert stages precisely where a change of state occurs by back tracking to pinpoint a change of state. For example, when an increasing pressure is detected, the software can now backtrack to when pressure was either stable or stopped dropping, and insert a stage precisely.


The audit trail now records use of logger and sensor calibration file at start of test or at start of CSV file import.


During manual calibration the operator is alerted for bath setting change.

When importing CSV file if units row is found the channel type is set to Type T regardless. Now it is set to type T only if the channel config channel type conflicts with units in CSV.


In I-Calc spec tab its now possible to change a selected group of I-Calcs for settings stage start/end and all the hide settings.


Report signatures can now be controlled with more options in setup options window.


The cal check report will now display the date/time of the calibration that is being checked. (Will only work on cal checks performed with new version.)


Now 60 characters are allowed for channel location field. But only 40 can be displayed in test setup report because of space.


TQSoft now stores data in a new format TQD file which allows use of floating point numbers thus removing the resolution limitation of 32000 in version 7.


Fix for advanced cal reference countdown timer which did not work in certain circumstance.


The TeamViewer quick support link was updated.


The advanced calibration report now does not repeat cal point operator information.

Correction for pressure calibration procedure where software asks user to adjust thermal bath!


Correction for advanced pressure calibration where check points were using uncalibrated data.


On start-up TQSoft 7 loads all the report references in Reports folder. With many reports this becomes very slow. Version 8 delays full loading until necessary.


Support for T&D loggers TRZ file format and T&D imports now create audit trail entries.


Export to CSV function is back which is a much faster export than the full export to Excel.


A continuously monitored I-Calc can now have a hysteresis in time format (hh:mm:ss) which allows limit checking only after a delay from start of monitoring.


Support for Graphtec firmware 1.28.

Dead backup battery causing issues is addressed.

Now allows 2 decimal places for thermocouples.

More support for reading secure GDB data files from the unit.

Correction to eliminate risk of endless loop freeze when TQSoft searches for its data files.


Support for humidity from dewpoint sensor. Its now possible to connect a dewpoint sensor to the logging unit and locate the sensor in the chamber. An I-Calc can be setup for each temperature and TQSoft calculates the humidity at that location without use of humidity sensors.


This update involves the inclusion of ‘continuously monitored I-Calcs’ in the chart and data list. A feature many engineers will appreciate as it allows calculations like deviations and averages on groups to be put on data list (in place of the basic calculations tab that uses all channels.)


Its now possible to mix THP and Gemini battery loggers with both time starting at zero and 24 hour format.


Correction for battery logger interface when assigning a logger to a test spec position.

February 14, 2018

TQSoft 7.1.0

·        Sensor groups are now supported. I-Calcs can reference group(s) and so a change to a group will automatically modify all the I-Calcs that use the group.

·        Temperature and humidity groups can now be summarized separately. (See also multi calculation below)

·        Validator 2000 latest firmware is now supported.

·        New driver for some TecnoSoft data loggers.

·        Updates to reports which now include printed on and by. Also ‘Performed by’ and ‘Reviewed by’ will appear more in reports and can be used either for electronic signature or for manual signatures.

·        Templates made with Designer now support trends. So right click on a calculation result and the software will collect data from date range of reports and make a trend in Excel.

·        Software can now log multiple chambers at the same time using one logger. Channel assignment changes are managed by the software so you can use the same test specification on the multiple chambers without worrying about channel references and locations etc.

·        New multi calculation introduced. It will store max, min, average, std dev and uncertainty. This means many times less I-Calcs are needed to produce summary sheets. The 7.1.0 install includes a sample test called ‘Stability Analysis 9 Temp 3 Humidity’ and it uses the new I-Calcs and groups to separate temperature and pressure. To illustrate there is a new summary sheet in Report Lists under ‘Sample Reports Stability/Stability Summary Channel 1-20’.

·        Bath and reference temperatures can now be logged, and bath temperature controlled by I-Calcs, for custom calibration procedures.

·        Fluke 1586A and 2638A default scan rate setting now depends on Fast/Medium/Slow setting. Also there is now a check box in Logger Control to always use the custom scan rate setting for calibrations.

·        Fluke 1586A and 2638A driver now supports resistance and thermistors.

·        Designer now supports look up tables for user entered data.

·        Legacy Fluke Hydra II drivers no longer reserve TQSoft channel 1 for the Fluke channel 001! J

·        3 Decimal place support for IRTD reference temperature.

·        Designer duplicate option will now auto increment probe numbers, making your time more productive!

TQAero 7.1.0

·        Chambers can be specified as cylindrical and the 3D wire diagram will support this.

·        Chambers can now have a work zone specified. The work zone can be seen in the 3D diagram and sensors positioned with respect to work zone.
