4. Design and function

4.4 Integrated data logger

From the firmware Version 3.00 onwards, the CPG1000 has an integrated data logger. This
data logger can be activated and operated using the CPGLog software. For this, see the
CPGLog operating instructions.

4.5 Power supply

The standard version is supplied with three AA batteries. In the optional 24V powered
version with an external power supply, the batteries are not installed. Connect the 24 V
power supply to the terminals at the rear of the measuring instrument. Ensure the polarity is
correct. Do not insert any batteries if an external power supply is being used.
WARNING!
Prior to connecting the mains adapter to the mains power supply make
sure that the operating voltage specified on the mains adapter matches the
mains voltage.
Measuring instruments with an external power supply unit are supplied
without batteries inserted. For operation with an external voltage source,
batteries MUST NOT be inserted. Measuring instruments with an external
power supply unit are not approved for the hazardous areas.

4.5.1 Battery replacement

WARNING!
The batteries must only be changed in non-hazardous areas.
Rotate the faceplate of the CPG1000 to the left by approx. 90° and remove it. After that the
front panel of the pressure gauge can be removed and the battery compartment is acces-
sible. For ATEX instruments remove the two screws on the rear of the enclosure to loosen
the front panel. Insert the AA-sized batteries with their polarity correct.
WARNING!
Always use AA batteries and observe the correct polarity. During enclosure
assembly ensure that the front is aligned properly.

4.5.2 Battery life time

The battery life time is 1500 hours (60 days) for continuous operation (without background
illumination). In the lower left corner of the display there is a symbol for the battery capacity.
This symbol appears if the battery voltage is too low. For instructions on batteries refer to
chapter "3. Specifications".
