Updates as of version 3.01.064 October, 2014

NEW version 3.01! This is a release version.

Added the new DT9826 Data Acquisition unit to avalilable equpment choices.

Added new window to enter the names for the DT982x units. These names no longer have to be ADIO-0 and ADIO-1 and only have to be changed in more than one unit is used on an instrument.

Added a new automatic Calibration Report option to create the report every time a calibration setup is performed.

Fixed the operation of the Cancel and Okay buttons on the Delayed Start window and changed display for better readability.

Fixed a possible problem if the delayed start passed December 31 into a new year.

Added minimum window size for main run-time window and graphs.

Updated the help file with new information and links from the software.

Added more information and better formatting in the Problem Report for better diagnostics.

Updates as of version 3.0.319 August, 2014

NEW version 3.0! This is a release version.

Now all major windows are completely sizable. All windows remember their last size and position on the screen. This makes working with many windows on higher resolution screens much easier.

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.

Fixed a minor problem where the "Insert Degree Symbol" button was left active in a column where it could not be used.

Fixed a problem where if loading a backup setting file the software could crash if an illegal parameter was encountered.

Fixed a problem where if a non-existing com port was selected for the rotating viscometer and then an experiment was run in demo mode the software could crash.

The main program now saves and restores all the settings for the Quick Reports.

Fixed a problem in Quick Reports that would generate an error if a graph was created with less than 10 data points in the data file.

Removed the 8 character filename limit on Quick Reports filenames. Reformatted those names and added the DateTime to them. Graph report names now include the actual name of the graph.

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.

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 2.30.0020; 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 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 (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.
