◆【End】: Press it and the last point on the last page will display.
◆ If more than two points with the same point name exist in the current
Coordinate file, the instrument finds the first point name data as you needing coordinate
date.

6.2 Azimuth Setting

The azimuth of backsight could be inverse calculated by the coordinates of instrument
station and backsight station.
N
see "§6.1 Input the occupied point data".
NOTE:
◆ You can input the azimuth angle directly in angle measurement mode.
6.3 3D Coordinate Measurement
The target coordinate could be measured after the setting of occupied point and
backsight azimuth.
The formular used to calculate:
N1＝N0＋S×sinZ×cosAz
E1＝E0＋S×sinZ×sinAz
Z1＝Z0＋S×cosZ＋IH－TH
