Intended use

The model CPH7000 process calibrator is a portable multi-function calibrator for the calibration of a variety of measuring
instruments. An integrated mechanical hand pump (optional) enables you to generate pressures up to 25 bar (360 psi); an
integrated electrical module also enables you to supply transmitters or sensors with a current of max. 30 mA (voltage (idling) =
DC 24 V), in addition to the typical measurement of current and voltage signals.
The process calibrator can be used to carry out and document a complete calibration process. In addition to the functions
of displaying, measuring and calibrating, the functions logging and switch test are also available. The use of the WIKA-Cal
software also allows a complete documentation.
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.
The manufacturer shall not be liable for claims of any type based on operation contrary to the intended use.

Improper use

DANGER!
Danger to life from explosion!
Improper use of the process calibrator causes a risk of explosion that can result in death.
The process calibrator should not be thrown into fire, since the built-in battery can explode.
WARNING!
Injuries, material and environmental damage due to an improper use of the process calibrator!
Improper use of the process calibrator causes a direct danger to life.
Do not throw the process calibrator into water → this can result in the destruction of the safety circuit, in heat
generation, in inflammation, in the formation of oxyhydrogen or corrosion and in the generation of electrolytes.
Overcharging, reverse charging and too high charging currents can result in fire or excessive gas formation.
The use of incorrect, unsuitable power supply units can lead to overheating, fire and to the destruction of the
rechargeable battery.
Crushing due to mechanical damage may result in the escape of electrolytes, in an internal short circuit, in
heating or fire.
WARNING!
Injuries through improper use
Improper use of the instrument can lead to hazardous situations and injuries.
Refrain from unauthorised modifications to the instrument.
Do not use the instrument within hazardous areas.
There must be no external pressure acting on the CPH7000.
Do not use the CPT7000 with abrasive or viscous media.
Only dry, clean air can be used as medium for the CPH7000.
It is forbidden to open the instrument.
Do not open the service flap on the rear. Only the manufacturer is allowed to open it.
Do not apply a voltage greater than the specified voltage to the instrument. See chapter 10 "Specifications".
Make sure that the test probes never contact a voltage source while the test leads are connected to the
terminals.
Do not use the CPH7000 if it is damaged. Before using the process calibrator, check that there are no cracks
or missing plastic parts on the case. Pay particular attention to the insulation of the connectors.
