Step
Procedure (Vacuum)
1.
Set to vacuum operation (-) (Ref: Item 3.1).
2.
Fully open the refill valve (Ref: Item 5.1).
3.
Wind the volume adjuster to mid-range or fully clockwise (Ref: Item 2.1).
Seal the system (Ref: Item 5).
4.
5.
Set the approximate vacuum with the pump (Ref: Item 3).
Adjust the vacuum with the volume adjuster (Ref: Item 2.1).
6.
7.
On completion of test, open the pressure release valve one turn (Ref: Item 5) to
release vacuum before disconnection of device under test.
7.2.3
Pressure operation
Step
Procedure (Pressure)
1.
Set to pressure operation (+) (Ref: Item 3.1).
2.
Turn the volume adjuster to mid-range (Ref: Item 2.1).
3.
Seal the system (Ref: Item 5).
4.
Use the pump to set a pressure up to ≈20 bar (300 psi) (Ref: Item 3).
5.
Open the refill valve (1 turn) (Ref: Item 5.1).
Increase or decrease the pressure with the volume adjuster (Ref: Item 2.1).
6.
If increasing pressure the limit of travel is reached, close the refill valve (Ref: Item
7.
5.1).
Wind the volume adjuster fully counter-clockwise. (Ref: Item 2.1).There is no
8.
change in pressure.
9.
Refill the pressure mechanism with the pump (≈15 cycles) (Ref: Item 3).
Wind the volume adjuster clockwise until the pressure starts to increase (Ref:
10.
Item 2.1).
11.
Continue to do steps 7 to 10 until you get the necessary pressure.
12.
