8 Battery replacement
Notice:
As soon as
BAT
appears at display, the battery needs to be replaced. If battery voltage power decreases
continuously, data logging will be stop
ped (compare with operating status ‘
HALT
’).
Available stored data remains in the memory and do not get lost. It’s possible to read the measuring data after
replacement of the battery.
The battery can only be replaced if the logger is opened and the sensor head and sensor is detached. This
has to be done with special diligence due to the danger of damaging the device.
Please note:
Malfunctions caused by inappropriate battery replacement are not included to guaranty.
If you do not want to replace the battery on yourself it is also possible to send the device to us. We will
replace the battery cost-effectively and appropriately.
Replacement:
1. Remove the 4 screws at the front of the logger with a
small screwdriver and remove the cover from housing.
2.
Screw off the sensor tube’s protective head.
Note:
The sensor is very damageable and not
protected any more. You have to handle it with
care and protect it from dirt.
3. Unplug the sensor by pulling it carefully to front. Touch
the sensor only in the range of the connection pins.
Note:
The connection pins can break if they are
inappropriately handled!
4. Pull off the white foam rubber to the front over the sensor-
connector.
5. Take out the PCB and deposit it carefully beside the
housing with the LCD display face down. Take care not to
damage the gasket.
6. Push out the button cell carefully from socket (in direction
of the arrow in the picture).
