2) Fully open the valve, slowly and carefully. You will notice any escaping air bubbles.

3) Close the valve again.
4) Turn the star handle further in a clockwise direction, until the test specimen and/or
the reference again indicates a pressure value of approx. 50 to 100 bar.
5) Fully open the valve, slowly and carefully. If necessary, check again if any air
bubbles escape.
6) Close the valve again.
7) Turn the star handle anticlockwise all the way out.
8) Open the valve.
9) After approximately 10 seconds, close the valve.
Repeat steps 1) to 9) again, if necessary.

3.2 Operation

We recommend unscrewing the spindle completely when you start to record
measurement values, (turning anticlockwise) to allow enough volume for measure-
ments.
To increase the test pressure turn the star handle clockwise.
To decrease the test pressure turn the star handle anticlockwise.
The use of a fine adjustment valve (CPP1000-L availabel as standard) allows to
make fine adjustments to the initial pressure setting by turning the fine adjustment
valve in or out.
The display of the instrument under test can be compared with the reference
measuring instrument at each individual calibration point.

The CPP1000-M/-L hand spindle pump is now ready to use.
For test specimens or reference instruments with particularly large
volumes we recommend filling them with operating liquid beforehand
or using the shut-off valve for test connection, which is available as
an accessory (see chapter 9. Accessories).
The maximum permissible pressure for the CPP1000-M/-L is
1000 bar. Higher pressures may damage the pump. The refer-
ence instrument, test specimen and any connecting tubes
that are used must not be subjected to pressures above the
maximum permissible level.
Since small amounts of air are always compressed in the system
together with the medium, the test pressure that has been generated
first drops off slightly. After this it must be readjusted.
