The refill valve (Section 1.4.4) sets the operation of the Volume
adjuster wheel: Full control or refill
When the refill valve is open, you have full control to increase
or decrease the pressure.
At higher pressures, it is easier to turn the wheel if you fold in
the handle:
1. Pull the handle out from the recess that locks it in position.

2. Fold the handle back against the wheel.

Refill
If you increase pressure and the volume adjuster gets to the
limit of travel, close the refill valve (Section 1.4.4). You can then
use the volume adjuster to refill the pressure mechanism:
1. Close the refill valve and then wind the volume adjuster fully
counterclockwise and clockwise until the pressure starts to
increase.
The counterclockwise operation refills the pressure
mechanism without a change in pressure to the device
under test or the PM 620 module (if applicable).
2. Open the refill valve to get full control again.
