Automatic Leveling
Automatic Leveling after Switching On
After switching on, the measuring tool checks
the horizontal position and automatically
compensates for irregularities within the self-
leveling range of approx. 5.7°.
The out-of-level indicator 37
flashes during leveling.
GRL 500 HV: Once it has been switched
on, the measuring tool automatically detects
the horizontal or vertical position. To change
between the horizontal and vertical position,
you can reposition it without switching it off.
Automatic Leveling during Operation
If after a position change the measuring tool
is outside of the self-leveling range of approx.
5.7°, leveling is no longer possible.
– In this case, realign the measuring
tool and then simultaneously press
/
the slope buttons 18 and 20 to
activate automatic leveling.
If the measuring tool is leveled, it constantly
checks the level position. Re-leveling is
automatically performed if there are any
position changes. To prevent incorrect
measurements, the rotation of the laser /
beam stops during the leveling process.
Single-axis Slope Operation
When the measuring tool is in the horizontal
position, the X-axis is automatically leveled
while in single-axis slope operation.
The rotational plane can be turned around
the X-axis in a range of ±8.5%.
Slope Setting
Slope setting is possible within a range of
±8.5%.
– Press and hold the slope
/
button 18 or 20 until the
desired slope value is
shown on the display.

Center Line Mode (see figure D)
In center line mode, the measuring tool
automatically tries to find the center line
by moving the rotation head upward and
downward.
Search Sequence:
1. Rotation head pivots upwards to the stop.
2. Laser beam is switched on.
3. Rotation head pivots downwards.
