2.2 Description

The model CPP7-H pneumatic hand test pump is used to generate pressure for testing,
adjustment and calibration of mechanical and electronic pressure measuring instruments
through comparative measurements in the low pressure range. These pressure tests may
be carried out in the laboratory, workshop, or on site at the measuring point.
If the instrument to be tested and a sufficiently accurate reference measuring instrument
are connected to the hand test pump model CPP7-H, the same pressure is applied to the
two measuring instruments when the pump is operated. By comparing the two measured
values at any given pressure value, the accuracy can be verified or the instrument under
test can be adjusted. To approach the measuring points exactly, the fine adjustment valve
of the CPP7-H can be used.
