3 Instrument station coordinates and Backsight station coordinates Input
14.3 Instrument station coordinates and
Backsight station coordinates input
*
The coordinates of the instrument setting surveying point (instru-
ment station) and those of a point whose coordinates are already
known (backsight station) can be input t o the SET2C.
*
The coordinatesof the backsight station are input in ordertoset the
horizontal angle in the X-axis direction t o 0' .
If the azimuth angle is already known, the following steps are
carried out:
1) Input only the coordinates of the instrument station.
2) Sight the backsight station.
3) Press @ J
t o turn Theodolite mode, and set the horizontal
angle t o the azimuth value.
Then skip the instructions in Section 14.4 and go directly t o Section
14.5.
To recall the instrument station coordinates and backsight
station coordinates from coordinate data stored on the IC
card, please refer t o P109.
