2.1 Intended use

This portable pressure calibrator serves as a calibration instrument for the widest variety
of pressure measuring instruments and has been designed for mobile use as well as for
stationary workshop and laboratory testing. Through the combination of the integrated
electrical pump and the electrical modules, in addition to the traditional measurement of
current and voltage signals it also enables you to supply transmitters or sensors with a
max. of 30 mA (voltage (idling) = DC 24 V). The pressure calibrator can be used to carry
out and document a complete calibration process.
WARNING!
Only use model CPT6000 reference pressure sensors!
■
Using other sensors could damage both the pressure calibrator and the
■
reference pressure sensor.
To change the sensor, switch off the pressure calibrator and make sure
■
the system is vented. Before switching the instrument on, connect the
sensor, otherwise it may not be correctly identified by the instrument.
When the CPH7650 is switched on, the CPT6000 reference pressure
■
sensor must not be under pressure, but rather should be at atmospheric
pressure. For overpressure or gauge pressure sensors, there is a
pressure compensation vent in the top of the sensor under the plastic
fitting. This vent (with integrated diaphragm) must always remain clear!
The instrument has been designed and built solely for the intended use described here,
and may only be used accordingly.
The technical specifications contained in these operating instructions must be observed.
Improper handling or operation of the instrument outside of its technical specifications
requires the instrument to be taken out of service immediately and inspected by an
authorised WIKA service engineer.
Handle electronic precision measuring instruments with the required care (protect from
humidity, impacts, strong magnetic fields, static electricity and extreme temperatures,
do not insert any objects into the instrument or its openings). Plugs and sockets must be
protected from contamination.
If the instrument is transported from a cold into a warm environment, the formation of
condensation may result in instrument malfunction. Before putting it back into operation,
wait for the instrument temperature and the room temperature to equalise.
The manufacturer shall not be liable for claims of any type based on operation contrary to
the intended use.
