DISTANCE MEASUREMENT SYSTEM CHAPTER 2
GEODIMETER SYSTEM 600
This measurement mode is normally used during control
surveys – e.g., traversing, minor tacheometric exercises,
survey point accuracy control, etc. Measurement time to each
point takes 3.5 seconds. This measurement mode is similar to
the one-face STD mode, the major difference being that
distance measurement is carried out in a repeated measure-
ment cycle thus resulting in higher accuracy.
The instrument carries out the measurement and display of
horizontal and vertical angles and slope distances. Horizon-
tal distance and difference in height, and the northings,
eastings and elevation of the point will all be displayed by
pressing the ENT-key twice. Collimation and horizontal axis
tilt errors are compensated and full angle accuracy can be
achieved with D-bar one-face measurements. The instrument
also offers the possibility of using the R.O.E. function in the
D-bar measurement mode (see page 2.2.10).
Note that when using the R.O.E.-feature the distance
measurement has to be interrupted by pressing the A/M-key.
Limited horizontal movement of the instrument telescope up
to 30 cm will result in the northings and eastings of the
measured point changing, also after pressing the A/M-key.
