– Simultaneously press the calibration
button 25 and the slope button 18 for
approx. 2 s.
The symbol for calibrating the X-axis is
shown on the display.
The out-of-level indicator 37 flashes dur-
ing automatic levelling.
– Wait until the measuring tool is levelled in.
– Use the laser receiver to find the centre line and transfer
the height "X1" of the centre line onto the wall.
– Turn the measuring tool 180° without adjusting the height
of the tripod.
– Wait until the out-of-level indicator 37 stops flashing and
the measuring tool is levelled in.
– Use the laser receiver to find the centre line and transfer
the new height "X2" of the centre line onto the wall.
– Determine the exact centre between the centre lines "X1"
and "X2" and position the laser receiver on it using the cen-
tre mark 16.
– Press the slope button 18 or 20 until
/ the centre line indicator 43 lights up
continuously. If the audio signal is
switched on, a continuous tone sounds.
– Press the calibration button 25 to save
the calibration.
The symbol for completing calibration is
shown on the display.
– In order to rule out faulty calibration after completion
of the calibration, you must check the levelling accuracy
(see "Checking the Levelling Accuracy in the Horizontal Po-
sition". page 44).
If the deviation is still outside of the maximum permitted
limit of ±1.5 mm, have the measuring tool checked by a
Bosch customer service agent.

Y-Axis Calibration

– Mount the measuring tool in the horizontal position on a tri-
pod 63 (accessory).
– Place the tripod 30 m in front of the wall. The Y-axis indica-
tor imprinted on the measuring tool must be pointing per-
pendicular to the wall.
– Switch the measuring tool on.
– Simultaneously press the calibration
button 25 and the slope button 20 for
approx. 2 s.

Z-Axis Calibration (GRL 500 HV)

– Mark a vertical line on the wall using a plumb line.
– Mount the measuring tool in the vertical position on a tri-
pod 63 (accessory).
– Place the tripod 5–10 m in front of the wall.
– Switch the measuring tool on.
– Simultaneously press the calibration
button 25 and the slope button 18 for
approx. 2 s.
The symbol for calibrating the Z-axis is
shown on the display.
– Align the tripod so that the laser beam crosses the vertical
line on the wall.
