Assembly
Inserting/Replacing the Battery
Using alkali-manganese or rechargeable batteries is recom-
mended for operation of the measuring tool.
To open the battery lid 10, press on the latch 9 and fold the
battery lid up. Insert the batteries/rechargeable batteries.
When inserting, pay attention to the correct polarity accord-
ing to the representation on the inside of the battery lid.
Always replace all batteries/rechargeable batteries at the
same time. Do not use different brands or types of batter-
ies/rechargeable batteries together.
Remove the batteries/rechargeable batteries from the
measuring tool when not using it for longer periods.
When storing for longer periods, the batteries/rechargea-
ble batteries can corrode and discharge themselves.
Operation
Initial Operation
Protect the measuring tool against moisture and direct
sun light.
Do not subject the measuring tool to extreme tempera-
tures or variations in temperature. As an example, do
not leave it in vehicles for longer periods. In case of large
variations in temperature, allow the measuring tool to ad-
just to the ambient temperature before putting it into oper-
ation.
