Indirect measurement
The instrument can calculate distances using Pythagoras proposition.
Make sure you adhere to the prescribed sequence
of measurement :
All target points must be in a horizontal or vertical plane.
The best results are achieved when the instrument is rotated about a fixed point
(e. g. with the positioning bracket fully folded out and the instrument placed on
a wall). Make sure that the first measurement and the distance to be measured
are at a right angle.
