New Automatic Load Cell!
Note: The following displays show the Dilatometer version of the software. Versions for other instruments are very similar.
Theta's DilaSoft I software features multiple interactive run-time graphics displays in a multitasking environment allowing an experiment to run while simultaneously analyzing previous experiment data.
The Main Menu is shown below. All instrument options are set through this menu program and the experiment is started from here.

The temperature program editing window displays the versatility and features available for this controlling feature of DilaSoft software. Displayed are the current program segment along with the previous segment at the top and the next segment at the bottom.

The Report Generator automatically gathers all the data about the experiment including the materials, temperature program, tables, dates, graphs and data and formats them into user selectable reports that can be saved to disk files for later use or printed immediately on the default Windows printer.
The run-time display shows all important information as the experiment progresses. The displays include: real-time bar graphs of both setpoint and specimen temperatures, strip chart recorder of expansion and temperature, temperature segment profile and much more. While the experiments are running, interactive graphs can be displayed showing expansion vs. temperature and/or expansion vs. time vs. temperature. Graph content varies according to the equipment being used. These graphs can be moved, sized and scaled while the experiment continues to run, giving the operator all necessary information about the experiment as it is taking place.

The Mini-Status window displays all the same information in a much smaller space, allowing other run-time graphs to be displayed without sacrificing screen space or viewed data.

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.
Data analysis remains unsurpassed in the industry offering the widest array of tools, charts, graphs, tables, printouts and reports. Analysis graphs and reports can all be completely customized by the user, printed immediately or saved to disk files for later retrieval.

Theta Industries has been the industry leader in thermal testing for over 30 years. We remain dedicated to bringing our customers the finest in both software and hardware to create the most advanced thermal testing equipment available.

Jump to segment
While an experiment is running, the user can now jump to any segment in the temperature program. this allows going back to an earlier segment for more data or to a later segment to end the experiment sooner.
Individual temperature program segment alarms
Every single temperature program segment (up to 100) can now have an alert alarm set. The two type of alarms are Timed and Timed with Pause. The Timed alert displays the alert window for the amount of time specified in the segment. The Timed with Pause displays the alert window for the specified time and also pauses program operation. Both alerts have audio/voice alerts.
User entered reference materials.
User entered reference materials can now be used in place of the standard reference materials supplied with the software. The list of materials can be saved and loaded independantly of the main software setup to allow changing the list of materials for different instruments.
Change-Over Height (or Deflection) for Viscometers
Change-over height (or deflection) for Parallel Plate and Bending Beam viscometers jumps to the next temperature program segment when the set value is reached..
Standard reference materials for Viscometers
Now includes 3 standard reference materials plus oil for the Rotating Viscometer.
Find Top of Melt for Rotating Viscometer
This feature will alert the user and pause the software, allowing time to precisely find the top of the specimen melt to adjust the depth of the rotor.
Temperature Correction files for Viscometers
This feature allows real-time data correction using temperature vs log of viscosity.
Temperature Program Cycling
Cycling allows program segments to be repeated up to 999 times for cycling tests. See the documentation for Program Cycling, in PDF format.
Mini-Status window
Displays all the information from the Main Status Window but in a much more compact space to save on screen space.
New 4-Head Mini Display
This window is 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.
Delayed Start
Great new feature that allows delaying the start of an experiment until a pre-set time.
Preheat the furnace
A new feature that allows pre-heating the furnace to a set temperature before an experiment starts. Very useful for thermocouples that do not return valid temperatures below a certain temperature. No more manually heating up the furnace!
Run-time priority can now be set
The software now has two available priorities for the run-time program. Our 'normal' has been 'high priority'. This can now be set to normal priority to allow more cpu time to other programs.
All new install program!
We now have an all new install program that fixes the minor problem the old installer had with some systems. The new installer is compatible with win95/98, NT and win2000. It's much more reliable and even prettier.
Correction files for both heating and cooling with the same ramp rate!
Correction files have been enhanced to allow using the same ramp rate for both heating and cooling cycles. The correction file documentation has been updated with new information. See the corfile.pdf for more info.
Enhanced graphs!
The run-time graphs can now display data from muti-head systems. The displayed data has increased from 2000 points to 6000 points for greater accuracy.
New Auto Specimen Length!
The auto specimen length feature for Dilatometers allows much faster experiment testing by freeing the operator from measuring the individual specimen lengths. Once set up in Calibration, the software automatically measures and records new specimens when the experiment is started.
New Auto Data Names!
The Auto Data Name feature frees the operator from selecting individual filenames for the saved data file and the experiment information file. This allows much faster repetitive sample testing. D/L or view the Auto Data Name docs.
New Dilatometer correction files!
Correction files guarantee absolute accuracy by measuring the differences of the components making up your particular instrument. View or download the documentation (updated 06/00) for more info.
New automatic load cell operation for the Dilatometers.
Much faster at up to 3 data points per second.
Dilatometer specimen lengths now up to 4 inches (100mm).
True multitasking!
More than one instrument can be operated at the same time from a single computer.
TMA calculations now available in analysis.
Increased resolution of the real-time strip chart display.
"None" can now be selected for the temperature controller, allowing a temperature program to still run and control mass flow valves and head speed while not controlling the furnace temperature.
Y2K Compliant!
A new Run-time Parameter screen allows real-time editing of key experiment parameters like the shrinkage limit, valve difference allowance, torque limits, etc.
Real time editing of the running temperature program allows the user to change the program while an experiment is running.
Proportional mass flow gas valve control.
Audible and visual messages for all warning, error and critical conditions. The software actually announces the messages verbally! And the verbal messages can be translated into any language by the user
For the Rotating Viscometer: Individual rotor speeds can now be set for each individual program segment. The original torque limits control can still be used.
For the Dilatometer: The maximum length a specimen expands to can now be used to calculate the shrinkage limit. This will prevent the meltdown of materials like glass that expands, then rapidly melts.
The Reset/Exit Temperature is now optional, allowing the furnace to remain at any temperature after the experiment is canceled or ends.
The "debug channel" interface has been enhanced to allow setting each channel while in the real time debug screen. This allows the user to see the actual voltages, temperatures, lengths, etc.
Familiar, user-friendly Windows interface throughout affording the flexibility to execute experiments and analyze data simultaneously.
All software features are fully documented in on-line Windows help files, accessible at any time.
Improved temperature profile programming accommodates 100 segments - each with its own data storage interval, valve settings and head speed for more efficient data collection. The entire profile is displayed graphically on screen and can be printed.
Complete display of all instrument configuration options, experiment features and run-time parameters.
User selectable reset temperature for safer experiment shutdown.
Instrument calibration is fully controlled through software. A selectable calibration interval reminds the operator when the equipment requires calibration.
