Fitting

Inserting/Changing the Batteries

It is recommended that you use alkaline manganese batteries to operate the measuring
tool.
Pull the locking mechanism (15) of the battery compartment cover outwards and fold
open the battery compartment cover (14). Insert the batteries.
When inserting the batteries, ensure that the polarity is correct according to the illustra-
tion on the inside of the battery compartment.
If the battery warning (a) appears on the display (6) for the first time, the measuring tool
can still be operated for approximately another two hours.
Always replace all the batteries at the same time. Only use batteries from the same man-
ufacturer and which have the same capacity.
Take the batteries out of the measuring tool when you are not using it for a pro-
u
longed period of time. The batteries can corrode and self-discharge during pro-
longed storage.
Operation

Starting operation

Protect the measuring tool from moisture and direct sunlight.
u
Do not expose the measuring tool to any extreme temperatures or variations in
u
temperature. For example, do not leave it in a car for extended periods of time. In
case of large variations in temperature, allow the measuring tool to adjust to the ambi-
ent temperature before putting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperatures or variations in temperat-
ure.
