To get an accurate height measurement use the GHM008 instrument height
meter in conjunction with the GHT196 distance holder. Both are included with
the scanner.
1. Place tripod centrally over the ground point, level instrument.

cover over an adjusting screw.
3. Unfold measuring tongue, pull out tape measure a little.
4. Insert GHM008 instrument height meter in the distance holder and
attach.
5. Swivel measure in the direction of the ground point, pull out until the
tip of the measuring tongue touches the point on the ground, keep
under tension and do not allow to sag, clamp if necessary.
6. Read height of the instrument (ground - tilt axis) in the reading win-
dow at the red marking (in the example 1.627 m).
