14. POWER SOURCE AND CHANGING THE BATTERY
The meter is powered by 9V battery or 12V stabilised power adapter. The
adapter should be joined with the
P connector (Pic.2). Connecting the power
adapter disconnects the battery and is signalised by the symbol.
The
symbol informs about the battery condition. Flashing of the
symbol informs that the battery should be changed. In order to do so, it is
necessary to undo two screws in the lower wall of the meter, pull out the
whole wall and replace the battery.
The next thing is to put the new battery into the meter and mount the wall.
The wall has a sealing ring at the edge. While closing the meter, it is very
important to pay attention if the ring is put inside the housing in the whole
perimeter. Next, do the screws till the moment of resistance (not too hard).
Leaving the wall improperly screwed may cause the meter’s inundation,
which is not repaired under the warranty conditions.
