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 burn or heat up the pressure calibrator.
▶Never store the pressure calibrator close to fire, ovens or other high-temperature locations.
▶Never put the pressure calibrator in microwave ovens, high-pressure containers or on induction hobs.
▶Never place the pressure calibrator in hermetically sealed containers. In some cases hydrogen or oxygen may
be discharged from the lithium-ion rechargeable battery, which may result in rupture, fire or explosion.
▶Never leave the pressure calibrator in direct sunshine or use or store them inside cars in hot weather. Doing
so may cause the lithium-ion battery to generate heat, explode or ignite. Using the lithium-ion battery in this
manner may also result in a loss of performance and a shortened service life.
▶Do not disassemble or modify the lithium-ion rechargeable battery in the pressure calibrator. It contains safety
and protection devices which, if damaged, may cause it to generate heat, explode or ignite.
DANGER!
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 allow the pressure calibrator to come into contact with water or salt water. It must never get wet.
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.
▶The use of incorrect, unsuitable power supply units can lead to overheating, fire and to the destruction of the
rechargeable batteries.
▶Do not pierce the pressure calibrator with nails or hit it with a hammer.
▶Do not step on or otherwise subject the pressure calibrator to strong shocks or vibrations.

3. Safety
Reference pressure sensors
■Always operate the reference pressure sensors within the overpressure limit.
■Reference pressure sensors should only be mounted or dismounted when the system is free from pressure.
■Only use model CPT6000 reference pressure sensors! Using other sensors could damage both the pressure calibrator and/
or the reference pressure sensor.
■If the reference pressure sensor is used in applications with oil as a pressure medium, make sure it is not be used with
flammable material or gases directly afterwards, since this can lead to dangerous explosions and a risk to personnel and
machinery.
Test leads and test probes
■Only use the test cable set available from WIKA for the pressure calibrator. Do not connect any cable over 3 m [9.84 in] long
to the CPH6000.
■Plan the wiring especially carefully when connecting to other devices. Under certain circumstances, internal connections in
third-party devices (e.g. GND connected to the ground) can lead to impermissible voltages that could compromise or even
destroy the function of the device itself or a device connected to it.
■Make sure that the test probes never contact a voltage source while the test cables are connected to the current terminals.
■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 test leads first.
■Disconnect test leads before changing to another measurement or source function.
Measuring mode
■There must be no external pressure acting on the CPH6000.
■Only use dry, clean air as a medium for the CPH6000 and CPT6000.
■Select the proper function and correct measuring range for the measurement.
■Always operate the reference pressure sensors within the defined pressure range.
■Should a failure occur, aggressive media under high pressure or vacuum may be present at the reference pressure sensors.
■The measuring signal of the reference (or test item) can be influenced by large electromagnetic effects and the display of
the signal may be lost completely.
Any use beyond or different to the intended use is considered as improper use.

Charging the lithium-ion rechargeable battery
If the lithium-ion rechargeable batteries become hot, the built-in safety and protective system is activated and overcharging
prevented. However, the heating of the lithium-ion battery can also destroy the safety and protective system and cause it to
heat up further, fail or ignite.
When the power supply unit is connected to the CPH6000, the lithium-ion battery will be charged, even if the
CPH6000 is switched off.
The typical charging time of the rechargeable battery is < 6 hours.
■The temperature range over which the lithium-ion battery can be charged is 0 ... 45 °C [32 ... 113 °F].Temperatures outside
of the specifications lead, during the charging process, to heating or destruction to the rechargeable battery. Furthermore,
the performance can be affected and the service life reduced.
■Extreme temperatures have an adverse effect on battery charging.Therefore, cooling down or warming up may be
necessary first.
