Pressure Sensors; Available Pressure Sensors; Connecting/Changing Pressure Sensors - WIKA CPH6200 Betriebsanleitung

4. Design and function
Disconnect the power supply unit from the mains supply when it won't be used for a
■
longer period of time.
The power supply unit is maintenance-free. It must not be opened (danger of electrical
■
shock).
Before cleaning, disconnect the power supply unit from the mains supply. Do not clean
■
with chemical cleaning agents. Only clean with a dry cloth.
The power supply unit enables a permanent power supply for the CPH6200
without using a 9 V battery or a 9 V rechargeable battery.
The power supply unit is not suitable for recharging the 9 V rechargeable
battery. The charging of the 9 V rechargeable battery must only be made
using an external charging unit.

4.5 Pressure sensors

CAUTION!
Damage to the instrument
If third-party reference pressure sensors are used, they can damage the
hand-held pressure indicator and the reference pressure sensor.
▶
Only use model CPT6200 reference pressure sensors!
▶
Only ever use the original WIKA sensor connection cable in the operation
of the CPT6200 reference pressure sensor.

4.5.1 Available pressure sensors

The hand-held has been designed so that all model CPT6200 pressure sensors can
be connected without the need for any readjustment. A wide range of interchangeable
sensors is therefore available, with ranges of up to 1,000 bar [14,500 psi], see chapter
10 "Specifications".

4.5.2 Connecting/changing pressure sensors

CAUTION!
Damage to the instrument
For overpressure or gauge sensors, the pressure compensation vent hole is
found at the top of the sensor housing.
▶
This vent (with integrated diaphragm) must always remain clear!
Before switching the instrument on, connect the reference pressure sensor,
otherwise it may not be correctly identified by the instrument.
1. To connect or change the reference pressure sensor, switch off the instrument.
