(e.g. direct sunlight).
B) Only non-conductive deposits occur, whereby occasional temporary conductivity
caused by condensation is expected.

Assembly
Inserting/Replacing Batteries (see figure A)
It is recommended that you use alkaline manganese batteries to operate the
measuring tool.
To open the battery compartment cover (5), press the locking mechan-
ism (6) and fold the battery compartment cover up. Insert the batteries/re-
chargeable batteries.
When doing so, ensure that the polarity is correct and corresponds to the
diagram on the battery compartment cover.
Battery Indicator
The battery indicator (b) always indicates the current battery status:
Indicator Capacity
90–100 %
60–90 %
30–60 %
10–30 %
0–10 %
The empty battery indicator flashes. You can measure for ap-
proximately another 15–20 min from when the flashing begins
until the tool shuts down.
Always replace all the batteries at the same time. Only use batteries from the
same manufacturer and which have the same capacity.
