2.3 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.
