WIKA Operating Instructions Test Pump
Test Pump
CPP30
1. Safety Instructions
Read these operating instructions carefully prior to operating
the pneumatic hand test pump CPP30. The pressure inside the
pump can be extremely high. Ensure that all pressure connec-
tions have been established correctly.
2. Product Description
Test pumps are used to generate pressures for checking, adjusting
and calibrating mechanical and electronic pressure measuring
instruments by comparative measurements. These pressure tests
may be carried out in laboratories, workshop or on site at the
measuring point.
If the instrument to be tested and a sufficiently accurate reference-
measuring instrument are connected up to the test pump, the
same pressure is applied to the two measuring instruments when
the pump is operated. By comparing the two measured values at
random pressure values, the accuracy can be verified or the
Instrument under test can be adjusted.
Despite its compact dimensions, the hand test pump model
CPP30 is easy to operate and allows for exact generation of the
required test pressures; a change-over switch enables the genera-
tion of vacuum as well. The pump is fitted with a fine adjustment
valve for the precise adjustment of pressures. The reference
instrument is screwed directly on to the top of the pump and the
unit under test is connected by means of the connection tube
incorporating an adapter 1/4" BSP female thread, contained in the
scope of delivery.
