2.5 Vertical and Horizontal Angle Tilt Correction
When the tilt sensors are activated, automatic correction of vertical and horizontal angle for
mislevelment is displayed.
To ensure a precise angle measurement, tilt sensors must be turned on. The display can also be used
to fine level the instrument. If the (TILT OVER) display appears the instrument is out of automatic
compensation range and must be leveled manually.
● GPT-7000i compensates both the vertical angle and the horizontal angle readings due to inclination
of the standing axis in the X and Y directions .
● For more information about dual axis compensation, see Chapter 17 “APPENDIX” .
● The display of Vertical or Horizontal angle 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. To set TILT
correction mode ON/OFF, refer to section 2.5.1 “Setting Tilt Correction by Soft Key”or Chapter 4
