Checking measurement
precision
See also from page 168.
Check precision of the measuring instrument
 before starting work,
 after large temperature changes
after violent impacts.

Before measuring angles up to 45°, check
the precision on a horizontal surface (~0°),
before measuring angles over 45°, vertical
surface (~90°).
Switch on the measuring tool and place it

on a horizontal or vertical surface.
Wait 10 seconds and make a note of the
measured value.
 Rotate the measuring tool (as shown in
the picture) 180° about the vertical axis.
Wait 10 seconds and make a note of the
second measured value.
NOTE
The measuring tool only needs to be calibrated if
the difference between both measured values is
greater than 0.1°!
Calibrate the measuring tool in the position
(vertical or horizontal) that the difference of the
measured values was determined in.

Calibration

Vertical contact surfaces
See also from page 170, figure A.
Place the contact surface on a surface

that is as vertical as possible. The surface
must not deviate more than 5° from the
vertical. If the deviation is greater, the
calibration will be aborted and the display
will show "---".
Switch on the measuring tool and place it

on the vertical surface in such a way that
the spirit level 2 points upwards and the
display 7 is pointing towards you.
Wait for 4 seconds!
Horizontal contact surfaces
See also from page 170, figure B.
 Position the contact surface on an even
surface that is as horizontal as possible.
The surface must not deviate more than
5° from the horizontal. If the deviation is
greater, the calibration will be aborted and
the display will show "---".
 Switch on the measuring tool and place it
on the horizontal surface in such a way
that the spirit level 1 points upwards and
the display 7 is pointing towards you.
Wait for 4 seconds!
