Operating the Test Kit

5.1 Generating the Pressure

The fi rst pumping process may require more physical effort due to the forces of
adhesion.
► Complete the fi rst pumping process with the pressure release valve open.
ATTENTION!
Risk of material damage to the test object due to excess pressure.
► Never exceed the maximum permissible pressure of the test object!
► Press the hand grips together carefully to generate a preliminary pressure
and slowly turn the fi ne adjustment valve clockwise to increase the pres-
sure!
The following methods of operation have proven successful in practice:
Single-handed operation
Reliable and easily con-
trolled pressure generation
up to 20 bar.
12
Two-handed operation
Reliable and easily con-
trolled pressure generation
between 20 and 40 bar.
Increase the pressure
from 40 bar using the fi ne
adjustment valve.
Non-slip base
Reliable and easily con-
trolled pressure generation
between 50 and 55 bar.
The bottom hand grip must
be positioned on a non-slip
base.
