1.3 Operation and maintenance advice

Battery operation status

If D and ´bAt´ are shown in the lower display the battery is low and
needs to be replaced. 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.
A) If the device is not going to be used for some time, we advise that
the battery is removed.
B) The real time clock has to be set again after reconnect to the
battery.
Connecting/Changing sensors

Only use sensors model CPT62I0. Using other sensors can dam-
age the instrument! Switch off device before changing the sensor
and connect the sensor before turning the device back on, other-
wise the sensor may not be identified correctly.
The CPH6200-Ex and the pressure transmitter are connected using a
discrete connecting cable. When changing the pressure transmitter,
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 CPH6200-Ex, the connector might
not locate properly in the socket. In this instance you should try hold-
ing the plug by the cable strain relief, rather than by the connector
housing. If the plug is correctly located, it will slide in smoothly. To dis-
connect the sensor hold it by the plug to release the connector lock.
Do not pull the cable to release it.
For gauge sensors, the pressure compensation vent hole is
found at the top of the sensor housing. This vent (with integral
membrane seal) must be kept clear without fail.
Maintenance advice

Both the CPH6200-Ex and sensors are manufactured using soli-
dstate technology, and contain no moving parts which could wear.
If the instrument housing has been opened, the warranty becomes
invalid.
If cleaning is necessary, use a cloth wetted with mild detergent. Avoid
any solvents, caustic or abrasive substances.
