2. Short overview
2.2 Description
The CPH7650 is a compact, portable pressure calibrator, which has been designed
for mobile use as well as for stationary workshop and laboratory testing. An integrated
electrical pump enables you to generate pressures up to 20 bar (290 psi) and an
integrated electrical module also enables you to supply transmitters or sensors with
a current of max. 50 mA (voltage (idling) = DC 24 V), in addition to the traditional
measurement of current and voltage signals.
The pressure calibrator can be used to carry out and document a complete calibration
process.The use of the WIKA-Cal software also allows a complete documentation. In
addition to the features of displaying or measuring and calibration, there is also a switch
test.

3.2 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 50 mA (voltage (idling) = DC 24 V).The pressure calibrator can be used to carry
out and document a complete calibration process.
This instrument is not permitted to be used in hazardous areas!
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.

3. Safety
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 pressure calibrator may result in a risk of explosion,
which may lead to serious injury or death, as the built-in lithium-ion
rechargeable battery may explode.
▶Do not throw the pressure calibrator into fire.
▶Never put the pressure calibrator in microwave ovens, high-pressure
containers nor on induction hobs.
▶Never place the pressure calibrator in a hermetically sealed container. In
some cases hydrogen or oxygen may be discharged from the lithium-ion
batteries, which may result in rupture, fire or explosion.
DANGER!
Injuries, material and environmental damage due to an improper use
of the pressure calibrator!
With improper use of the pressure calibrator, an immediate risk to life can
exist, as the built-in lithium-ion rechargeable battery could heat up or ignite.
▶Do not burn or heat up the pressure calibrator.
▶Never store the pressure calibrator close to fire, ovens or other
high-temperature locations.

3. Safety
WARNING!
Injuries, material and environmental damage due to an improper use
of the pressure calibrator!
Improper use of the pressure calibrator causes a direct danger to life.
▶Do not throw the pressure calibrator into water this can result in the
destruction of the safety circuit, in heat generation, in ignition, in the
formation of oxyhydrogen or corrosion and release of electrolytes.
▶The use of incorrect, unsuitable power supply units can lead to
overheating, fire and to the destruction of the rechargeable battery.
WARNING!
Injuries or damage to property through improper use
Improper use of the instrument can lead to hazardous situations and injuries.
▶Refrain from unauthorised modifications to the instrument.
▶Do not open the front panel of the calibrator!
▶Do not use the instrument within hazardous areas.
▶Only use model CPT6000 reference pressure sensors! Using other
sensors could damage both the pressure calibrator and the reference
pressure sensor.
▶There must be no external pressure acting on the CPH7650.
▶Only use dry, clean air as a medium for the CPH7650.
▶Observe the operating parameters in accordance with chapter
10 “Specifications”.
▶Make sure that the test probes never contact a voltage source while the
test cables are connected to the current terminals.
▶Do not use the calibrator if it is damaged. Before using the instrument,
check that there are no cracks on the case or any missing plastic parts.
Pay particular attention to the insulation of the connectors.
▶Select the proper function and correct measuring range for the
measurement.
▶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 instrument.
▶When using test probes, keep fingers away from the test probe contacts.
Keep your fingers behind the test probes' finger guards.
▶First connect the neutral conductor, and then the live lead.When
disconnecting, remove the live test lead first.
▶Disconnect test leads before changing to another measurement or source
function.
▶To avoid false indications, which could lead to possible electric shock or
injuries, charge the integrated rechargeable battery as soon as the battery
indicator appears.
▶To ensure trouble-free operation, only operate the instrument on battery
power. Only use the power supply unit for charging the instrument's
batteries.
