6. COORDINATE MEASUREMENT

6.1 Execution of Coordinate Measurement

Measure the coordinates by entering the instrument height and prism height,
coordinates of unknown Point will be measured directly.
* When setting coordinate values of occupied point, see Section 6.2 "Setting
Coordinate Values of Occupied Station Point".
* When setting the instrument height and prism height, see Section 6.3
"Setting Height of the Instrument" and 6.4 "Setting Height of Target (prism
Height)".
* To set backsight, determine the backsight azimuth or check the known
azimuth, coordinate and distance.
The coordinates of the unknown point are calculated as shown below and displayed：
Coordinates of occupied point： （N0，E0，Z0）
Instrument height :INS.HT
Prism height: R.HT
Vertical distance (Relative elevation)：Z（VD）
Coordinates of the center of the prism, originated from the center point of the
instrument： （n，e，z）
Coordinates of unknown point： （N1，E1，Z1）
N1=N0+n
E1=E0+e
Z1=Z0+INS.HT+Z－R.HT
Center point of the instrument (N0, E0, Z0+INS.HT)
