What is PressCal
Pressurements PressCal software (PressCal) provides a quick and effective solution to
enhance the pressure measurement accuracy of Deadweight Testers (DWT). PressCal
provides an easy-to-use GUI (Graphical User Interface) that allows you to calculate all
the necessary corrections needed (such as local gravity, temperature etc.) to accurately
determine the pressure generated by your DWT.
PressCal also provides:
Chapter 1
Overview
• Automatic certificate generation
• Customer details management
• Real-time auditing
How Does It Work
PressCal works from first principles using the actual DWT pressure equation:
=
P
e
By using a combination of data files and your environmental/working details, PressCal
can achieve true accuracy and consistency in its calculations.
System Requirements
The following system specifications are required as a minimum to successfully install and
run the PressCal software:
• Microsoft® Windows 95 or higher
• 486 PC with maths coprocessor
Installation
Double click on setup.exe, then follow the online PressCal installation instructions.

System Operation
This software only runs if you have purchased the correct software version and installed
it into the default C:\PressCal directory.
The software keeps the last setup and other settings in a configuration file (PressCal.cfg)
so that on power-up the user can carry on from the last settings prior to power down.
To maintain the accuracy and security of the software, the PCU’s and Weight Sets’ data
is preloaded by SI Pressure Instruments.
Future upgrades are available from SI Pressure Instruments on a chargeable basis
provided the software users can provide mass and effective area calibration data of the
relevant Deadweight Testers.
Getting Started
Double click on the "PressCal" icon or alternatively click on Start> Programs
>PressCal > PressCal.

Correction Parameters
The “Correction Parameters” area shows the current configuration for the calibration.
The area comprises both information that is read-only (obtained from related files) and
fields that can be modified directly allowing you to finely tune the correction parameters.
Weight Selection Details
The “Weight Selection Details” area shows the Type, Identity and Corrected Mass for
each weight within the currently selected weight set (identified by the
“Weight Set S/No:”).

The table can be used to highlight the weights that are required to produce a particular
pressure, or alternatively weights can be selected within the list and the resultant pressure
is then shown taking into account the correction parameters.
A weight is selected within the list by double-clicking on it, the row is then highlighted
and a cross (X) is shown immediately adjacent. To unselect double-click on the
highlighted row. For further information refer to Performing a Calculation.
