Z-Axis Calibration - Bosch GRL2000-40HV Operating Instructions Manual

– Make sure the laser is turned off.
– Mark a vertical line on the wall using a plumb
line.
– Mount the laser level in the vertical position on
a tripod or a firm and level surface.
– Place the laser level in front of a 30 ft (10 m)
high wall.
– While holding the button for dual-axis slope op-
eration 2, press and release the On/Off button
1. Release the button for dual-axis slope opera-
tion 2 when the X axis leveling indicator LED
5 (green) and shock-warning indicator LED 11
(red) start flashing simultaneously at a rate of
1x per second.
– Wait until the tool is leveled - the prism will start
rotating.
– Align the laser level so that the laser beam
crosses the vertical line on the wall.
– Using the lower/upper direction button 4 or 12
adjust the laser beam until it is as parallel as
possible to the vertical line on the wall.

– If you are not able to match it, repeat the previ-
ous steps (align tripod, allow measuring tool to
level in, align laser beam using the lower/upper
direction buttons 4 and 12).
– Press the button for dual-axis slope operation 2
to save the calibration.
– The X axis leveling indicator LED 5 will flash 6
times.
If during adjustment, the X axis leveling indicator
LED 5 starts flashing red the deviation is outside
of the maximum permitted limit. Pressing the but-
ton for dual-axis slope operation 2 will exit the cali-
bration mode without saving the new value and an
error will be shown by flashing the X and Y axis
leveling indicator LEDs 5 simultaneously at a rate
of 3x per second. Restart the calibration and if the
error persists, have the laser tool checked by a
Bosch customer service agent.
Check the leveling accuracy after calibration. If
the deviation is still outside of the maximum per-
mitted limit, have the laser level checked by a
Bosch customer service agent.
