3.3.3 Execution of Coordinate Measuring
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 3.3.1“Setting Coordinate Values of
Occupied Point” .
● When setting the instrument height and prism height, see Section 3.3.2“Setting of the Instrument
Height / Prism Height” .
● The coordinates of the unknown point are calculated as shown below and displayed:
Coordinates of occupied point : (N

Instrument height : Inst.h
Prism height : R.h
Vertical distance(Relative elevation) : z
Coordinates of the center of the prism,
originated from the center point of the instrument : (n,e,z)
