1.2 Safety instructions

2. Product description

The CPP 7 hand test pump is used to generate pressure for checking, adjusting and calibrating
mechanical and electronic pressure measuring instruments by comparative measurements in the low-
pressure range. These pressure tests may be carried out in laboratories, workshops 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 measure valves at random pressure values, the accuracy
can be verified or the instrument under test can be adjusted.
The CPP 7 is a pneumatic hand test pump for low-pressure ranges up to 7 bar with change-over
switch to vacuum generation down to -850 mbar. Despite its compact dimensions, the hand test pump
CPP 7 is easy to operate and allows for exact generation of the required test pressures. The
maximum pressure or vacuum achievable depends on the attached test volume. The smooth-running
pressure generation and the integrated fine adjustment valve allow a safe and precise setting of very
small positive respectively negative pressure values in the range of mbar.
The test device and the reference instrument can be easily connected by means of a T-connector with
tube connection.
