DISTANCE MEASUREMENT SYSTEM CHAPTER 2
GEODIMETER SYSTEM 600
Distance Measurement
Overview
The distance module of Geodimeter System 600 operates
within the infrared area of the electromagnetic spectrum. It
transmits an infrared light beam. The reflected light beam is
received by the instrument and, with the help of a compara-
tor, the phase delay between transmitted and received signal
is measured. The time measurement of the phase delay is
converted and displayed as a distance with mm accuracy on
the four-line LCD.
When taking measurements with servo instruments and
having the Tracker installed there may be a distance error if
you use large prisms. See page 2.2.9 for further information!
The internal function of the distance measurement module
can be varied depending on the nature of the particular
survey application in question. There are four methods of
distance measurement.
The choice of measurement method is often based on the
experience of the operator and of course the practical preci-
sion demanded by the current survey task.
Standard measurements towards stationary targets
(standard mode)
Fast measurements towards stationary targets
(fast standard mode)
Precision measurements towards stationary targets
(arithmetical mean value D-bar mode)
Measurements towards moving targets (tracking mode)
e.g., setting out or hydrographic surveying. Also functions
as automatic measuring mode for polar measurement and
tacheometry.
