the direction of the laser) or backwards (in the direction of the display).
Otherwise the measuring accuracy may deteriorate.
Digital spirit level
The measuring tool checks horizontal or vertical like a spirit level. Laser
lines are not projected.
The side of the laser aperture serves as a reference edge. For angle meas-
urement, align this reference edge with the horizontal or vertical plane
that is to be measured. When doing so, do not tilt the measuring tool more
than 5 ° forwards (in the direction of the laser) or backwards (in the direc-
tion of the display). Otherwise the measuring accuracy may deteriorate.

Working Advice

 Always use the centre of the laser line for marking. The width of the
laser line changes with the distance.
Calibration of the inclinometer without laser lines (e. g. before the in-
itial operation, after transportation or severe temperature fluctua-
tions):
Place the measuring tool on a flat table with a tilt of less than 5°. Select the
digital spirit level mode. Hold down the "Cal" calibration button 3 until
CA1 flashes on the display. After a short time, the tick f appears and CA1
is shown continuously. Rotate the measuring tool 180° within 15 seconds
and hold down the "Cal" button 3 again until CA2 flashes on the display.
The calibration is completed once the tick f appears on the display and
CA2 is shown continuously.
Accuracy Check of the Measuring Tool
Regularly check the accuracy of the grade measurement. This is done by
carrying out a reversal measurement. For this, place the measuring tool
on a table and measure the grade. Turn the measuring tool by 180 ° and
measure the grade again. The difference of the indicated reading may not
exceed by more than 0.3 ° (max.).
Working with the Tripod (see figure H)
A tripod 12 offers a stable, height-adjustable measuring support. Place
the measuring tool via the tripod mount 6 onto the 1/4" male thread of the
tripod and screw the locking screw of the tripod tight.
