Note: Do not pry the battery lid 18 open with auxiliary
aids if difficult to remove. Otherwise it can become
damaged.
Battery-pack Operated Measuring Tools
The measuring tool is provided with the battery pack
installed. Before putting into operation for the first
time, remove the safety strip in the battery compart-
ment ("Remove before Use").
Charge the battery pack before using for the first time.
The battery pack can only be charged with the battery
charger 19 provided.
Connect the appropriate charge cable for your mains
supply to the battery charger 19.
Switch the measuring tool off. Insert the charger plug
20 of the battery charger into the socket 15 on the
measuring tool. Connect the battery charger to the
mains supply. Charging the empty battery pack takes
approx. 10 h. The battery charger and the battery
pack are protected against overcharging.
A battery that is new or has not been used for a longer
period does not develop its full capacity until after
approx. 5 charging/discharging cycles.
Do not charge the battery pack each time after using,
otherwise its capacity will be reduced.
When the indication "ERROR/BATTERY LOW"
appears in the display, the battery pack must be
charged. When the battery pack is empty, the measur-
ing tool can also be operated with the battery charger
19. Switch the measuring tool off and connect the bat-
tery charger to the measuring tool and to the mains
supply. When the battery pack is deeply discharged, it
must be charged for approx. 15 minutes before the
measuring tool can be switched on and operated with
the connected battery charger.
A considerably reduced operating period after charg-
ing indicates that the battery pack is used up and
must be replaced.
To change the battery lid with installed battery pack,
loosen nut 14 and remove the battery lid 18.
Install a new battery lid 18 with battery pack. Pay
attention that the contacts 17 of the battery lid and the
contacts 16 of the battery compartment are aligned
properly and have contact. Firmly tighten the battery
lid with nut 14.
Remove the battery pack from the measur-
ing tool when not using it for longer periods.
When storing for longer periods, the rechargeable
batteries can corrode and discharge themselves.

Battery-operated Measuring Tools
Alkali-manganese batteries are recommended for the
measuring tool.
The measuring tool is provided with batteries inserted.
Before putting into operation for the first time, remove
the safety strip in the battery compartment ("Remove
before Use").
When the indication "ERROR/BATTERY LOW" ap-
pears in the display, the batteries must be replaced.
To open the battery compartment, loosen nut 14 and
remove battery lid 18.
When changing the batteries, pay attention to the cor-
rect polarity according to the representation on the
inside of the battery lid.
Always replace all batteries at the same time. Only
use batteries from one brand and with the identical
capacity.
Mount the battery lid 18 again. Pay attention that the
contacts 17 of the battery lid and the contacts 16 of
the battery compartment are aligned properly and
have contact. Firmly tighten the battery lid with nut 14.
Operation

Initial Operation

Remove the batteries from the measuring
tool when not using it for extended periods.
When storing for extended periods, the batteries
can corrode and discharge themselves.
Protect the measuring tool against direct
sunlight.
Do not subject the measuring tool to extreme
temperatures or variations in temperature. As
an example, do not leave it in vehicles for longer pe-
riods. In case of large variations in temperature, al-
low the measuring tool to adjust to the ambient tem-
perature before putting it into operation. In case of
extreme temperatures or variations in temperature,
the accuracy of the measuring tool can be impaired.
Avoid heavy impact to or falling down of the
measuring tool. After severe exterior effects to
the measuring tool, it is recommended to carry out
an accuracy check (see "Accuracy Check of the
Measuring Tool", page 26) each time before con-
tinuing to work.
