Assembly
Inserting/Replacing the Batteries (see figure A)
Using alkali-manganese or rechargeable batteries is recommended for oper-
ation of the measuring tool.
To open the battery lid 5, press on the latch 6 and fold the battery lid up. In-
sert the batteries. When inserting, pay attention to the correct polarity ac-
cording to the representation on the inside of the battery lid.
Battery Indicator
The rechargeable battery/battery indicator b always displays the current bat-
tery status:
The battery is over 90 % charged
The battery is between 60 % and 90 % charged
The battery is between 30 % and 60 % charged
The battery is between 10 % and 30 % charged
The empty battery indicator flashes. The battery charge status is un-
der 10 %. You can measure for approximately another 15–20 min-
utes from when the flashing begins until the tool shuts down.
Always replace all batteries/rechargeable batteries at the same time. Do not
use different brands or types of batteries/rechargeable batteries together.
 Remove the batteries/rechargeable batteries from the measuring
tool when not using it for longer periods. When storing for longer peri-
ods, the batteries/rechargeable batteries can corrode and self-discharge.
Mounting the Leg Extension
Slide the leg extension 17 onto the fold-out leg 1 from the front. Observe the
arrow on the leg extension when doing so. Slide the leg extension as far as
possible over the joint of the measuring tool.
Operation

Initial Operation

 Protect the measuring tool against moisture and direct sun light.
 Do not subject the measuring tool to extreme temperatures or varia-
tions in temperature. As an example, do not leave it in vehicles for a long
time. In case of large variations in temperature, allow the measuring tool
to adjust to the ambient temperature before putting it into operation. In
case of extreme temperatures or variations in temperature, the accuracy
of the measuring tool can be impaired.
