If the instrument is a type CPH 6200-Ex intrinsically-safe hand-
held pressure indicator, the additional safety instructions
regarding the Ex-operation described in Section 8 must be
strictly observed.

1.2 Operation and maintenance advice

Battery Operation
If ∆ and ´bAt´ are shown in the lower display the battery is low
and needs to be replaced or recharged (using the appropriate
battery charger as shown in the current CPH 6200 price list ).
The device will, however, work normally for a limited period. If
´bAt´ is shown in the upper display the voltage is too low to
operate the device; the battery will be completely flat.
If the device is not going to be used for some time, we advise that
the battery is removed.
Mains operation with power supply
When using a power supply please note that the operating
voltage must be 10.5 to 12 V DC. Do not use with higher
voltages! Cheap 12 V-power supplies often have excessive no-
load voltage, and we therefore recommend using regulated-
voltage power supplies. Trouble-free operation can be ensured
by using our own power supply unit (see current CPH 6200
price list). Before connecting the power supply to the mains
make sure that its operating voltage matches the local mains
voltage.
Connecting/Changing Sensors
Only use sensors model CPT 6200. Using other sensors can
damage the instrument! Switch off device before changing the
sensor and connect the sensor before turning the device back
on, otherwise the sensor may not be identified correctly.
The CPH 6200 and the pressure transmitter are connected using a
discrete connecting cable. When changing the pressure transmit-
ter, always connect and disconnect at the transmitter end of the
cable. To connect the transmitter, rotate the plug till it locates in
the guide slot, allowing it to plug in. Then tighten the safety collar
(by screwing it lightly in a clockwise direction).
When connecting the cable to the CPH 6200, the connector might
not locate properly in the socket. In this instance you should try
