Replace the battery. Place the battery
lid with the battery holder into the
measuring tool in such a manner that
the connection cables are not trapped.
If the measuring tool is not
used for a long period of time,
the battery must be removed.
The battery can corrode or dis-
charge itself over long periods.
Operation
Initial Operation
Protect the measuring tool
against moisture and direct sun
irradiation.
Do not expose the measuring
tool to extreme temperatures
or variations in temperature.
Switching On and Off
Press the "ON/OFF" switch 7 to
switch the measuring tool on or off.
After approx. 6 minutes without per-
forming a measurement, the measuring
tool switches off automatically in order
prolong the service life of the battery.
Checking the Measuring Accuracy
(see figure D)
Check the accuracy of the measuring
tool each time before using, after
extreme temperature changes as well
as after heavy jolts or impact.
Before measuring angles <45°, the
accuracy check should take place on a
level and roughly horizontal surface;
before measuring angles >45°, on a
level and roughly vertical surface.
Switch the measuring tool on and
place it on the horizontal or vertical sur-
face.
Select the unit of measure "°" (see
"Changing the Unit of Measure").
Wait for 10 s and note down the meas-
ured value.
