5.4.1 Pressure Procedure
1. Close the pressure release valve fully clockwise.
2. Close the refill valve fully clockwise.
3. Turn the volume adjuster fully clockwise and then fully counter-clockwise until the pressure
starts to increase.
Continue this sequence (clockwise / counter-clockwise operation) until the necessary
pressure is reached, or for full control, go to step 4.
Note: Turning the volume adjuster counter-clockwise refills the pressure mechanism.
During refill, there is no change in pressure to the equipment under test or the PM 620 /
PM 620 - IS / PM 620T / PM 620T - IS module.
4. Open the refill valve (1 turn).
5. Use the volume adjuster to adjust the pressure: (+) decrease; ( - ) increase.
Note: At high pressures, it is easier to turn the wheel with the handle folded in.
6. If the volume adjuster reaches the end of its travel, close the refill valve fully clockwise (finger
tight only).
7. Turn the volume adjuster fully counter-clockwise.
8. Repeat steps
2 to 7 until the necessary pressure is reached.
5.5 Add More Hydraulic Fluid
If the equipment under test has a large fluid capacity, it may be necessary to add more hydraulic
fluid during a test.
1. Close the refill valve fully clockwise (finger tight only).
Note: Closing the refill valve seals off all pressure in the test port and the pressure module
connection.
