2. Description / 3. Tools and accessories
_ The tool can be set up on a tripod with a
5/8" thread or stood directly on some
other steady surface.
_ The tool is easy to operate, robustly built
and comparatively light in weight.
2.3 Description of functions
2.3.1 Horizontal plane
(automatic leveling)
When switched on, the tool levels itself
automatically by way of the 2 built-in servo
motors for the X- and Y-directions.
2.3.2 Inclined plane (manual adjustment
to any desired slope)
Inclination can be set up in alignment with
given marks or contours by pressing the X-
and Y-keys.
2.3.3 Automatic cut-out
During automatic leveling in one or both
directions, the servo system monitors
compliance with the specified accuracy.
The tool switches itself off in the following
situations:
– Leveling is not accomplished (tool set up
outside leveling range or mechanism
physically impeded)
– The tool is brought out of level (due to
vibration or impact)
After automatic cut-out, rotation of the
laser beam stops and all LEDs blink.
