4. Operation (pressure) .
 Make sure, the CPP 700-H or CPP 1000-H is in priming position. If necessary, press the switching
knob
(7).
Switching knob (7)
handles in position - priming - - high pressure generation
 Make sure that the release valve (2) is open.
 Turn the adjustment valve (4) counter-clockwise fully out (smooth “stop” can be felt)
 Turn the release valve (2) clockwise until the vent is closed.
 Operate the handles (8) for priming, until the handles (8) are just before they cannot be pressed
fully together anymore, due to the generated priming pressure. Depending on the volume of the
calibration circuit, this can be at app. 200 to 400 bar / 3000 to 6000 psi.
 Keep the handles (8) pressed together and operate the switch knob (7). The handles (8) are now in
“high pressure” position.
NOTE: if the generated priming pressure is too high and - as a result - it is no longer
possible to press the handles (8) fully together, please open the release valve (2) (turn
counter-clockwise) and try it again.
 Operate the handles (8) until the required pressure is nearly achieved, but max. to app. 600 bar /
9000 psi. Higher pressure is made by turning the adjustment valve (4) clockwise.
NOTE: After increasing the pressure, the reading may slightly drop again for about 30
seconds, which is caused by thermodynamic effects, the tube connection and the
sealing gaskets. If the pressure drop does not come to a standstill, check the
measuring circuit for tightness.
