DilaSoft V3 updates, fixes and additions

See special hardware compatibility note below:

This page contains information about the latest DilaSoft V3 32-Bit software updates, fixes additions and changes. If you are using DilaSoft V3 for Windows with a version prior to 3.x, please see the enhancements and fixes below and upgrade your software for guaranteed future support and compatibility.

For addition documentation, see the DilaSoft V3 software page and software docs page. Also see the DilaSoft V3 registration information page.

Our software is constantly being enhanced and updated. We are always open to add new features and options. If you have any suggestions or needs, please contact Rich directly. Some of our best ideas have come from our customers!

Special support note: The most reliable and fastest way to get DilaSoft V3 software support is to e-mail me directly. I respond to e-mails very quickly and more details can be transferred than by any other means. If you have a DilaSoft V3 software problem, make sure to create a Problem Report from within the software and attach that file to the e-mail.

Please note: Due to current circumstances, direct and free support for DilaSoft I software sold by theta industries (any version) has been discontinued as of May 1, 2015. If you have a problem or question about any version of DilaSoft I sold by theta industries, CONTACT THEM! I am sorry for this inconvenience and will do my best to answer any E-mails concerning DilaSoft V3 software. I will not be able to get involved with lengthy support issues. Those will have to be handled by theta industries as will any hardware problems. Of course I offer full software support for any registered versions of DilaSoft V3 purchased through Bearly Computing!

DilaSoft V3 version 3.5 is done.

Theta Industries finally paid an invoice (last year!). Hoping this was a good sign ( it wasn't ), I released DilaSoft V3 version 3.20.111 to them. If you purchase this new version through theta industries, make sure it is registered in your name! I can not send the license code if the registration fee has not been paid to me in full!

Unfortunately as of November 2015, it doesn't look like theta industries will be distributing any versions of DilaSoft V3 beyond the old 2014 version 3.01.064. If any other dilatometer / viscometer manufacturers would be interested in distributing DilaSoft V3, feel free to contact me. If your system can be controlled by computer, I can make DilaSoft V3 work with it. I can also brand the software to your company.

To be clear, DilaSoft V3 is the latest version of the old DilaSoft I software sold through theta industries. They no longer distribute the latest versions.

If you are interested in the latest version just send me an e-mail...

The Lock Configuration setting feature can now be password protected. This helps prevent accidental changes to the system configurations in environments where students or lesser trained people operate the instrument. Added the user reference materials editing to the lock/unlock.

Many changes made to the user interface to make it easier to use.

Finally removed the flicker on the run-time strip chart graph.

Fixed a problem when loading a temperature program file that would retain the old program name and write over the old program.

Fixed a problem where the graph names were not correct for a particular instrument in the run-time program.

Added a new feature to archive all experiment information into a single file contained in a new EXPArchive folder. This file contains all information needed to completely restore the software to the state used when the experiment was run including the data file and temperature program. This feature also has an Auto-Archive option that creates this archive file after every experiment run.

Completely new handling of the rare printer crash problem with the Analyze program. A separate program is first loaded to test the crash, invisible to the operator. Analyze will now simply run with no problems.

The analyze program now creates a log by default for better diagnostics.

Fixed a problem where if loading settings from a backup file a blank line would be inserted into the temperature program.

Made the Problem Report compatible with the settings restore and archive functions.

Added the option of WMF (windows meta file) file format output for the Quick Report graphs. Advantage: much smaller file size and can be sized up or down to any size without loss of resolution.

Fixed a problem with the runtime program where if any program segment after the first had a ramp rate set to zero, the segment would not be processed correctly.

With the DilaSoft Analyze program, the .prn extension no longer must be typed in when using the Save As menu feature. The standard PRN extension will automatically be added now.

Enabled the Restore Original menu feature. This feature reloads the original data file.

For the analyze program, the backup filename extension has been changed from .bak to .prb. This allows the program to load a backup data file directly if needed. A data file can not be saved directly with a .prb extension for safety.

Fixed a minor problem in the analyze program where if a data file was loaded, then any plot generated, then the same file was selected to load from the file menu (by clicking on the last used filename), a bad file name error was generated and the data file was not loaded. This now works correctly.

Fixed the automated file association between the DilaSoftAnalyze program and prn, pr1-4 and prb extensions.

The main DilaSoft program no longer disappears when the "data analysis" button is clicked on to open the DilaSoftAnalyze program.

Fixed DilaSoftAnalyze to allow only one instance of the program to run. All instance checking code has been rewritten for better function and compatibility.

The default installation folder and filenames have changed. Version 3.x can be installed and run without affecting an older version 2.x installation.

Many small fixes and changes to both unseen code and visible user interfaces...

The help files have been updated with the new screens and information of new or changed features.

Updates as of version 2.42.1000; January 18, 2002

Fixed a problem when using very long directory/folder path names.

Added support for new Brookfield DVIII+ rotating Viscometer head.

Updates as of version 2.42.0000; December 12, 2001

Added option to use Rotating Viscometer in Poise instead of centiPoise.

Added tungsten material for specimen holder.

Modified setpoint routines to use actual specimen temperature instead of setpoint temperature for many settings including error/fault conditions so furnace temperature would not change adversely.

Improved reporting in Problem Reports.

Updates as of version 2.41.0007; September 10, 2001

Added automatic calibration for the balance of the TGA instrument.

Updates as of version 2.41.0000; August 27, 2001

Added Theta Alumina 410 to list of reference materials for compatibility with available alumina materials..

Repaired TGA functionality which has been broken since version 2.36.0011.

Fixed default DTA channel settings as two channels were left on that should have been turned off when instrument type was changed.

Fixed right Y axis of run-time dual graph display.

Modified run-time graph printouts for darker lines and colors.

Fixed Main program channel setup for channel title input to prevent non-standard character inputs which prevented the analyze program from properly loading the resulting data files.

Many cosmetic and minor functional changes made to make program operation more clear and standard.

Updates as of version 2.40.0017; May 17, 2001

Added User Reference Materials for Dilatometers and Viscometers!

Updates as of version 2.37.0000; May 8, 2001- Interim release.

Added Change-Over Height to Parallel Plate Viscometer.

Added Change-Over Deflection to Bending Beam Viscometer.

"Change-Over" height & deflection is a user setting that forces the software to jump to the next temperature program segment when reached.

Updates as of version 2.36.0011; April 20, 2001

Standard reference materials have been added to the Viscometers. These include: Borosilicate glass, Lead-Silica glass, Soda-Lime-Silica glass and oil (for the rotating viscometer).

Temperature Correction files have been added to the viscometers. This new correction file type functions with temperature vs the log of viscosity instead of delta-length. See the Software Additional Documentation page for more information.

Support for the new Keithly KPCI-3107/8 data acquisition cards have been implemented. The software has been modified to now support up to 100 separate devices over the old limit of 10 devices for future expansion.

A new feature for the Rotating Viscometer is "Find top of melt". This option alerts the user at a set point in the experiment so that the top of the specimen melt can be found to properly adjust the depth of the rotor.

A correction was made to the TGA handling of correction file data.

Fixed a minor problem with the error report generation.

Greatly improved the speed of operation when using the 3194 20-bit data acquisition box.

Updates as of version 2.30.0061; October 23, 2000

The temperature program graph now correctly plots the cycles of a cycled temperature program.

An precision error in the volume calculation for the Parallel Plate Viscometer was corrected.

Updates as of version 2.30.0050; October 6, 2000

The run-time status screens now display the time remaining for the currently running temperature program segment.

The Analysis program now has a built-in graph for the specimen length vs temperature (for Dilatometers).

Updates as of version 2.30.0020; September 11, 2000

Three completely new features added again!

New Mini-Status window. This is a smaller version of the run-time Status window that uses less screen space but displays all the experiment information.

New Temperature Program Cycling. Allows the repetition of program segments for cycling experiments.

New 4-Head Mini Display window just for multi-head Dilatometers. This new mini window displays the temperature, position and thermal expansion for all 4 heads at the same time, constantly updated and able to be positioned anywhere on the screen.

The total time for temperature program runs is now displayed in the main Program Tab window.

For Dilatometers, the actual current specimen length is now saved in the data file.


Updates as of version 2.20.000; August 1, 2000

Two completely new features added!

Pre-Heating the furnace. This feature allows the operator to use a pre-heat temperature program to heat the furnace to a specified temperature before the experiment actually starts.

Delayed Start. This feature (only available in the Full version) allows the operator to set a starting time for the experiment. The software will wait until that set time before starting the experiment.

Analyze has been updated to fix a recent problem with the parallel plate and bending beam Viscometer table reports. The graph "save-as -> BMP" function is now operational again.
A minor addition of computer up-time has been added to the Problem Report.

Updates as of version 2.13.000; July 13, 2000

Extensive work has been done to the Problem Report generator. Much more information is now reported not only about our software, but also about the computer running it. This will help immensely with solving problems running the software on customer supplied machines.
The new help file is now fully integrated into the software. The new help file is now completely multi-instrument. Each instrument has it's own complete help section. This offers clearer and more in-depth information without having to read about the other instruments.
We now have an "update" program that automatically installs any upgrade programs, files and components and even backs up the replaced files.

Updates as of version 2.12.008; June 20, 2000

The new install program is now being used on the distribution CD's. This fixes many small problems with the old installer and guarantees compatibility with win95/98, NT and win2000.

Correction files now work for both heating and cooling cycles using the same ramp rate. See the new correction file documentation (in PDF format) for details.

Many modifications to data collection routines for greater reliability, accuracy and error checking. It was possible that an over-range condition on the data acquisition could cause a 'spike' return data point that would generate a "meltdown" error condition. This would force the software to jump to the next cooling cycle or end the experiment. This has never been reported without a definite corresponding hardware failure. However, this should no longer be possible as the software now checks for 'spike' conditions before generating the errors.

The display of the run-time graphs has been increased from 2000 points to 6000 points for greater resolution and accuracy.

Updates as of version 2.11.004; May 16, 2000

A requested new feature has been implemented. For 4 head Dilatometers, any or all of the 4 head measurements (thermal expansion and temperature) can now be displayed in the two run-time graphs. Each of the 4 heads are selectable by color coded buttons. This does not include the run-time strip chart!

In the analyze portion of the software, the average alpha between any two points of the data file can now be calculated.

The run-time program priority can now be set in the Configuration menu. This allows a setting of 'normal' instead of the high priority the software usually runs with. This will allow more CPU time to other applications for better multitasking.

Updates as of version 2.10.255; May 11, 2000

A potential problem has been found and corrected involving the use of correction files in experiments with temperature programs containing both heating and cooling program segments. This is only a problem if both heating and cooling segments are used, and both heating and different cooling correction files are used in the same experiment. New correction file documentation (in PDF format) is available to clarify the correct procedure for this type of use.

Updates as of version 2.10.250; May, 2000

4 Head Dilatometer:

All 4 correction files are now correctly used. If you use the 32-Bit DilaSoft and have a 4 head system, you should make sure your version is at least 2.10.250!

Overall faster operation when using 4 correction files.


Bending Beam and Parallel Plate Viscometers:

Viscosity can now be displayed as Poise or Log of Poise during the experiment. This is set from the drop-down menu and is remembered between sessions.

Absolute position column in the data file is now in centimeters to coincide with the rest of the measurements.

Parallel Plate maximum load is increased to 1000 grams.


Rotating Viscometer:

New software based zeroing function for the high sensitivity head. This is much more accurate and prevents erroneous result with certain spindle sizes or shapes and material properties. If the proper zero can not be established, the user is notified and the experiment is aborted.



The internal relays of the ADC16 data acquisition board are now linked to software switches 1 and 2. These allow for the direct control of higher current external devices.

Spaces are now allowed in filenames.

The drop-down menu option for Help->search now functions.


Special Hardware Compatibility Note:

Hardware support note: Up to the current version of DilaSoft V3, all original hardware is still supported by the software. However, much of the older hardware can no longer be tested, probably can not work with current versions of windows and is no longer actively supported. These hardware devices include: 3194 Data Acquisition, Daytronic System 10, National Instruments ADC, DA1600 Int.Data Acquisition, ADC16 Int.Data Acquisition, TGA Cahn Balance, K3107 Data Acquisition, MR1S 2 Color Pyrometer. If your instrument uses one of these devices and you want to upgrade to the latest version of DilaSoft V3, please contact us for solutions. The 3194 Data Acquisition should have no problems with compatibility. The Keithley K3107 should work up to windows 7 (32 bit only). The Mark IV dial guage, Cahn balance and pyrometer may also work as they are RS-232 devices, however they are no longer manufactured and can not be tested.

*The DTA/TGA systems can no longer be tested and verified as these instruments have not been manufactured in many years.

For the Data Translation DT982x data acquisition units, make sure you have installed at least version 7.6 of the DT OpenLayers drivers!
