5.1.2 Tilt Setting
When the auto tilt correction function of the vertical and horizontal angles is turned ON, the 2-axis tilt
sensor is activated, and tilts in vertical and horizontal angles due to inclination of the standing axis will
be corrected automatically.
To ensure precise scanning, use the instrument with the auto tilt correction ON. If the tilt is out of
automatic compensation range, [TILT OVER] display will appear on the screen. In such case, level the
instrument. When the tilt comes into the automatic compensation range after the leveling, the screen
will automatically return to the display before the [TILT OVER] display.
z GLS-1500 compensates both the vertical angle and the horizontal angle readings due to inclination
of the standing axis in the X and Y directions.
z The display of inclination of the X and Y directions is unstable when instrument is on an unstable
stage or a windy day. You can turn off the auto tilt correction function of V/H angle in this case.
