5.1 Maintenance
The measuring instrument is almost maintenance-free.
The only maintenance task is replacing the batteries. LoBat indicates
that the batteries should be changed. The batteries are then largely de-
pleted.
Replacing the batteries
Warning
Make sure that the poles of the batteries are the right way round.
The
± signs on the batteries must correspond to the ± signs in the bat-
tery compartment. Only use leakproof alkaline manganese batteries.
1 Open the housing after the instrument has been switched off:
– Undo the four screws on the underside of the instrument
– Pull down the lower cover (1).
2 If necessary, take the four depleted batteries (2) out of the bat-
tery compartment.
3 Place four new batteries (type Mignon AA) in the battery com-
partment.
