DISTANCE MEASUREMENT SYSTEM CHAPTER 2
GEODIMETER SYSTEM 600
The tracking measurement mode is used for setting out with
the option of using countdown to zero of both the horizontal
bearing (azimuth) and distance to the setting out point. The
instrument very quickly calculates the difference between the
present direction and the required direction to the point to be
set out and the difference between the horizontal distance
measured and the required horizontal distance to the point.
These differences are visible on the display and when both
the dHA (difference in horizontal angle) & dHD (difference
in horizontal distance) = 0 ("countdown to zero"), the range
rod is then being held over the required setting out point.
The actual setting out can be carried out in two different
ways in the standard version of the instrument:
Tracking measurement ( Setting Out)
TRK
Keying in of bearings (SHA), distances (SHD) and height
(SHT) to the points, after first calling up F27 (SHA), F28
(SHD) and F29 (SHT) respectively.
Keying in of instrument station data (including instrument
height =IH) and set out point data by using the main menu,
Option 3, Coord, choices 1 and 2. The instrument will then
calculate the bearing (SHA), the horizontal distances (SHD)
and the height (SHT), between the instrument station point
and each individual keyed in setting out point. After setting
out the point and checking the point coordinates and eleva-
tion, you re-enter the main menu and key in the coords and
elevation of the next setting out point. For more informa-
tion see Page 1.4.27.
