3.1 Battery / rechargeable battery operation
Use only alkaline-manganese batteries, type IEC 6 F22. At a current con-
sumption of around 4.5 mA, these last for an operating time of approx. 80
hours. If sensors or modules also requiring power are connected, the opera-
ting time will be accordingly shorter.
Inserting the batteries:
The battery compartment (7) is located under-
neath the device.
1. Press on the spot marked with the arrow and at
the same time pull in the direction shown by the
arrow (as shown in the illustrations).
2. Connect the battery using the clip. Accidental re-
verse polarity is prevented by the shape of the
connections.
3. Use the second battery compartment to store a
reserve battery.
Battery check:
If the battery symbol in the display lights up, this me-
ans that the battery will last for approximately another
5 hours. (Supply voltage <7 V)
In the event of the battery voltage falling below 6 volts,
the display shows the message ´
LobAt
´. In this event
the battery must be removed immediately. This pre-
vents the battery from leaking and thus damaging the
device
The current battery voltage can be checked by applying a mea-
suring channel with ‘Battery voltage’ set as range.
Tips on the correct handling of batteries:
Never leave used dead batteries in the device !
If the device is likely to be unused for a relatively long time, remove the batteries !
A leaking battery represents a health hazard and may also destroy the device.
Use only leak-proof batteries !
