Measure Pressure – TERPS USB
5.6 Measure Pressure – TERPS USB
TERPS (Trench Etched Resonant Pressure Sensor) UPM is a resonant silicon pressure sensor
that gives high accuracy and high precision pressure measurement with a digital output. It can be
used with the DPI620G using USB communication to increase the calibrator functionality.
Before using a TERPS module, please refer to the user manual (K0473, Druck TERPS
80
00/8100/8200/8300 Series).
Note: To attach a TERPS module to the DPI620G calibrator, use a Micro-USB cable to connect
the module to the DPI620G.

5.6.1 TERPS Option Instructions
1. Attach one end of the micro-USB cable to the TERPS module.
2. Push the other type A end of USB cable into the USB socket on the instrument.
3. Energize (power on) the instrument.
5.6.2 TERPS Function Procedures
Set the applicable channel options:
1. On the external sensor channel , select the TERPS function or any TERPS related option
from the Task menu.
2. If necessary, change the Units for the function.
3. If necessary, set a Utility for the function i.e. Max/Mean/Min, Switch Test or Leak Test.
4. If required, change the Process settings for the TERPS function (Tare, Alarm, Filter, Flow,
Scaling)
5. The zero procedure is the same for a TERPS module as for a PM620 / PM620T module. Zero
a gauge sensor before use. See Section 5.8 for details on zero operation.
