5.
Close the
Oil Reservoir Valve
. If the
Pump Isolation Valve
is closed then the
pump will not be used to recharge the oil side during operation.
a.
Open the High Side Gas Interface Valve.
b.
Open the Low Side Gas Interface Valve.
6.
Connect the DUT high pressure test port to the High Side Gas Port of the
RUSKA 2482
.
7.
Connect the DUT low pressure test port to the Low Side Gas Port of the
RUSKA 2482
.

Warning
All tubing and fittings used to connect the DUT to the
RUSKA 2482 must be rated for safer operation to at least
2975 psi (205 bar).
W
Caution
The High Side Oil Port and Low Side Oil Port of the
RUSKA 2482 are not used in this test and must be capped or
plugged.

1.
Verify the High Side Oil Port and Low Side Oil Port are capped or plugged.
2.
Select
to activate the motor rotation.
3.
Select
to activate the pressure control bias to increase control
capacity. This will allow the system to stabilize at the pre set bias, refer to the
Software section (Windows | PIDValue — Operation Power %). This will take
approximately 15 minutes prior to a calibration sequence to provide the maximum
control capacity for the system. This may be unnecessary for short calibration cycles.
4.
Close the
Gas Exhaust Metering Valve
. For barometric line pressure do not open
the
Gas Supply Metering Valve
. Otherwise, carefully open the
Gas Supply
Metering Valve
to produce the desired line pressure.
5.
When the thermal effects caused by the change in the line pressure subside and the
Tared Reading in the Control Screen is stable, then select
. The
Tare status should display a numeric value. If the Tared Reading is zero then zero
differential pressure is applied to the test instrument.
6.
Set the
Oil Isolation Valve
to Isolate. Set the
Gas Isolation Valve
to Isolate.
Apply weights corresponding to the desired differential pressure.
7.
Operate the
Gas Exhaust Metering Valve
and the
Gas Supply Metering
Valve
to produce the desired differential pressure to within 3 grams as indicated by
the Tared Reading in the controller screen, then select
. When the
control system regulates the differential pressure for a Tared Reading of zero, the
desired differential pressure is applied to the test instrument.
