4.3.3 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 4.3.1“Setting Coordinate Values
of Occupied Point” .
• When setting the instrument height and prism height, see Section 4.3.2“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 0 , E 0 , Z 0)
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)
Coordinates of unknown point : (N 1 , E 1 , Z 1 )
N 1 = N 0 + n
E 1 = E 0 + e
Z 1 = Z 0 + Inst.h + z - P.h
Confirm the angle measurement mode.
