Operating Instructions
3.1
Set up
Place the unit on a stable table.

Check the calibrator for damages.
Plug the power supply cable in socket at the right hand side of the unit.
Control the voltage power supply indication before plug in.
3.2
Operating Instructions
The TRAQC-8 DPC is a differential pressure calibrator with a maximum of 75 bar line pressure and is designed
on customer request. The calibrator includes a high pressure reducer which has to be fed by an external
pressure source of maximal 200 bar (refill connection) or by the internal gas bottles. On the pressure outlet
of the Pressure control valve are a Supply valve, and a high precision volume controller for fine adjustment
of the test pressure.
3.2.1
Preparations before bring on pressure to test connections
Before set up pressure to the calibrator, ensure that:
The Mode selector valve must be in position “Equalize”
The sensing e and – are interconnected, so pressure is equal at both sides of
the pressure sensor. Before switching the Mode selector valve to position “Measure”,
make sure that both pressures at Test + and Test – are within the measure range of the
instrument
When the calibrator will be used without external pressure supply, ensure that the gas
bottles are filled to maximum to ensure high pressure during the test procedure;
See 2.3 for instructions for refilling the gas bottles
When the calibrator will be used without external power supply, ensure that the battery
of the calibrator is charged to maximum to ensure power during the test procedure.
See 2.6 for instructions how to charge the battery
The Heise volume controller which is needed to set a differential pressure, is turned to
the middle of the range
(30
turns clock wise from fully clockwise on)
The Pressure control valve is turned fully counter clockwise
The Supply valve is turned fully counter clockwise
The Balance valve of the Heise volume controller must be set into vent mode (pull)
The Relief (vent) valve is turned fully clockwise
