6.4 Operaon (pressure generaon)
a) Make sure that the pressure test pump is in priming posion. If necessary, press the switching
knob (toggle) (2).
Handles in posion...
„priming pressure“
„high pressure“
The toggle / switching knob (2) can be operated only, if both handles (1) are pressed
together. Otherwise a too high priming pressure is generated.
b) Make sure that the release valve (5) is open.
c) Turn the adjustment valve (7) counter-clockwise fully out (smooth „stop“ can be felt).
d) Turn the release valve (2) clockwise unl the vent is closed.
e) Operate the handles (1) for priming, unl
priming pressure are generated.
max. 50 bar
f) Keep the handles (1) pressed together and operate the switch knob / toggle (2). The
handles (1) are now in „hig pressure“ posion.
NOTE:
If the generated priming pressure is too high and - as a result - it is no longer possible
to press the handles (1) fully together, please open the release valve (5) (turn counter-
clockwise) and try it again.
g) Operate the handles (1) unl the required pressure is nealy achieved, but max. to approx.
600 bar / 9000 psi. Higher pressure is made by turning the adjustment valve (7) clockwise.
NOTE:
Aer increasing the pressure, the reading may slightly drop again for about 1-3
minutes, which is caused by thermodynamic effects, the tube connecon and the
sealing gaskets.
If the pressure drop does not come to a standsll, check the measuring circuit for
ghtness.
