Z-Axis Calibration; Working Advice - Bosch GRL 600 CHV Notice Originale

50 | English
The relevant error message will ap-
pear in the measuring tool display if
calibration of the X‑axis or the Y‑axis
has not been successful. "ERR" will
appear on the display of the laser re-
ceiver.
Cancel the calibration with
pressing the button for line
operation (5).
Make sure that the measuring tool and the laser receiver are
aligned correctly (see description above). Restart the calib-
ration.
If calibration fails again, have the measuring tool checked by
a Bosch customer service agent.

Z-axis calibration

A free measuring distance on firm ground in front of a 10 m
wall is required for the calibration. Fix a plumb line to the
wall.
Position the measuring tool on a firm, level surface. Switch
the measuring tool on and allow it to level in. Align the meas-
uring tool so that the laser beam is perpendicular to the wall
and cuts through the plumb line. Switch the measuring tool
off.
To start calibration mode, press and hold the slope
button (14) and then also briefly press the on/off
button (11). The measuring tool is switched on. Allow the
measuring tool to level in.

Align the laser beam so that it runs as parallel as possible to
the plumb line.
If it is not possible to align the laser beam in parallel to the
plumb line, align the measuring tool to the wall more pre-
cisely and start the calibration process again.
If the laser beam is aligned in parallel, save the calibration
with by pressing the slope button (14).
If the calibration has been completed successfully, the
measuring tool then automatically switches itself off.
Ensure that the reference vertical line is in the pivoting range
of the rotation head and restart the calibration. Make sure
that the measuring tool is not moved during calibration.
If calibration fails again, have the measuring tool checked by
a Bosch customer service agent.

Working Advice

Only the centre of the laser point or laser line must be
u
used for marking. The size of the laser point/the width of
the laser line changes depending on the distance.
The measuring tool is equipped with a wireless inter-
u
face. Local operating restrictions, e.g. in aeroplanes
or hospitals, must be observed.
Tilt the laser beam in the ◀ direction
by pressing the ▲ button (4). Tilt the
laser beam in the ▶ direction by
pressing the ▼ button (3).
This symbol confirms that the Z-axis
has been calibrated successfully. At
the same time, the status
indicator (12) will flash green three
times. End the calibration with
pressing the slope button (14).
This error message will appear if calib-
ration of the Z-axis has been unsuc-
cessful. Cancel the calibration with
by pressing the button for line
operation (5).
