• Flip the Level over 180° (see figure below) and
press the
CALIBRATE
button. The number 2 will start
to flash after a few seconds. This will indicate that
the calibration has been completed.
• The unit will automatically shutoff if it is stationary
for three minutes.
NOTE: An incorrect calibration will occur if there is too
much deviation in the horizontal calibration positions, or if
the level has been shaken.
MAINTENANCE
Store and transport the digital level only in the supplied
protective case. Keep the tool clean at all times. Do not
immerse the tool into water or other fluids. Wipe off de-
bris using a moist and soft cloth. Do not use any cleaning
agents or solvents.
Checking the Measuring Accuracy
Check the accuracy of the digital level each time before
using, after extreme temperature changes as well as after
heavy jolts or impact.
The accuracy check should take place on a level and
roughly horizontal surface. Power ON the digital level and
place it on the horizontal surface.
Select the unit of measure “°”. Wait for 10 seconds and
note down the measured value.
Rotate the digital level by 180° around the vertical axis.
Wait again for 10 seconds and note down the second
measured value.
Calibrate the measuring tool only when the difference
between both reading values is greater than 0.1°.
CALIBRATION
NOTE: When the ambient temperature changes consider-
ably, a calibration will be in order to maintain the accuracy
of measurements.
• Press the “
