-mm + 34.4
Example:
Non-Leica Geosystems prism
constant = 14 mm
=>Prism constant to be entered
= -14 + 34.4 = 20.4
Limit value:
-999 mm to +999 mm
Angle Settings
Tilt Correction
Off Compensator switched
off.
On Compensator (2 axes)
switched on. V-angles
relate to plumb line and
the Hz-angles are
corrected for the tilt of the
standing axis.
If the instrument is used on an
unstable base (e.g. shaking
platform, ship, etc.) the
compensator should be
switched off.
This avoids the compensator
drifting out of its measuring
range and interupting the
measuring process by indicating
an error.
The compensator setting
remains active even
after the instrument is switched
off.
