DISTANCE MEASUREMENT SYSTEM CHAPTER 2
GEODIMETER SYSTEM 600
The Geodimeter instruments have an automatic signal
control which adjusts the measurement signal level for the
optimal value for each distance measured.
The infrared measurement beam has a width of 16 cm/100m
(≈6 inch/300 feet)(1.6 mrad). The wide measurement beam
simplifies considerably both target/prism acquisition and
setting out exercises.
The Geodimeter instruments have an range capability of
0.2m to 3500m (depending on the type of instrument) with
only one prism in normal weather conditions (Standard
clear).

Important information when measuring with high accuracy
To achieve the highest accuracy when measuring distances
shorter than 200 meters and having the Tracker unit
installed on your instrument you need to be aware of the
following:
If you use a large reflector like the Super Prism (Part no. 571
125 021) or the Tiltable Reflector (Part No. 571 126 110)
you need to cover the tracker aperture before you measure
the distance. Otherwise reflections from the Tracker unit
may have influence on the measured distance. The error can
vary from 0 to 3 mm. If you use a Miniature Prism (Part no.
571 126 060 or 571 126 100) this error doesn't occur.
Since the Geodimeter instruments are constantly improved
we refer to the Technical Specifications sheets for the up-to-
date accuracy figures of the respective models.
