2.2 Description
The model CPH7000 process calibrator is a battery-powered, precise, portable calibrator for the on-site calibration and
checking of analogue pressure measuring instruments, pressure transmitters and process transmitters. Furthermore, pressure
switches can be checked and the switch point determined.With the CPH7000, not only can transmitters be checked, but also
simulated and tested.
The integrated hand pump (optional) enables you to generate a pressure of up to 25 bar (360 psi).This pressure can be
measured by means of an integrated pressure sensor (optional, available only in conjunction with the pump).
For pressure ranges of -1 ... 10,000 bar (-14.5 ... 145,000 psi), the model CPT7000 external precision pressure transmitter is
available. In conjunction with the data logger, it is also possible to carry out a leakage test in a very simple manner.

3. Safety
3.2 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.
3.3 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.
▶Select the proper function and correct measuring range for the measurement.

▶When using the electrical module, set the measurement type first and then connect the connection cables.
▶Only tighten the vent valve by hand, as it is a needle valve.Tightening with excessive force can result in a
damage of the needle valve or the sealing.
▶Inspect the test leads for damaged insulation or exposed metal. Check the continuity of the leads. Damaged
test leads should be replaced before using the process calibrator.
▶When using test probes, keep fingers away from the test probe contacts. Keep your fingers behind the test
probes' finger guards.
▶First connect the common lead, and then the live lead.When disconnecting, remove the live test lead first.
▶Disconnect test leads before changing to another measurement or source function.
▶When the battery indicator lights up red, load the rechargeable battery of the CPH7000, in order to avoid an
incorrect display or a data loss.
▶To avoid any damage to the process calibrator or to the inspection equipment, always use the proper
connection cable, function and area for the respective measuring application.
▶The switch valve can be switched from positive pressure to vacuum or from vacuum to positive pressure only
in depressurized state.
▶Only use the accessories specified and authorized by WIKA.
▶If pressure is applied over a long period of time, the pump can be damaged.
▶Only use pressure sensors model CPT7000! The use of other pressure sensors can result in the destruction of
the measuring instrument and of the pressure sensor.
▶Make sure that the internal sensor is not overloaded by the pump.
The electrical module can generate max. 30 mA and DC 24 V and measure max. 30 mA and DC 30 V.
With the integrated pump, pressures from -0.85 ... +25 bar (-12.3 ... +360 psi) can be generated.
Any use beyond or different to the intended use is considered as improper use.
3.4 Responsibility of the operator
The instrument is used in the industrial sector. The operator is therefore responsible for legal obligations regarding safety at
work.
The safety instructions within these operating instructions, as well as the safety, accident prevention and environmental
protection regulations for the application area must be maintained.
The operator is obliged to maintain the product label in a legible condition.
3.5 Personnel qualification
WARNING!
Risk of injury should qualification be insufficient
Improper handling can result in considerable injury and damage to equipment.
▶The activities described in these operating instructions may only be carried out by skilled personnel who have
the qualifications described below.
Skilled personnel
Skilled personnel, authorised by the operator, are understood to be personnel who, based on their technical training,
knowledge of measurement and control technology and on their experience and knowledge of country-specific regulations,
current standards and directives, are capable of carrying out the work described and independently recognising potential
hazards.
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.
