6.5 Connection of the model CPT6000 reference pressure sensor

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!
CAUTION!
Only ever use the original WIKA sensor connection cable in the operation of
CPT6000 reference pressure sensors.

6.6 Voltage supply

The internal Lithium-Ion battery, which can be easily charged with the battery charger
supplied with the equipment, serves as the voltage supply for the instrument. To charge
the CPH7650 rechargeable batteries, the mains plug of the charger/power supply unit
must always be plugged into a mains socket and accessible, so that one can always
remove it from the mains socket without difficulty.
CAUTION!
For EMC reasons, never use the CPH7650 with a power supply unit
connected.
The instrument should be fully charged before being put into operation.
The battery capacity status (charge state in %) is displayed shortly after the instrument
is switched on and can be learnt about in chapter 6.4.5 "SETUP additional menu items:
CPH configuration".
When the mains lead is connected to the CPH7650, the battery will be
charged, even if the CPH7650 is switched off
