(3) Inputting the height of prism
If you wish to measure the Z coordinate of target point,
the height of the prism must be entered.
In < Coord.Meas./Setup> menu, press [F3] to
select"Prism height".Input the height of the prism
used, then press [OK].
4.3.2 3-D Coordinate measurement
The coordinate values of the target can be found by measuring the target based on
the settings of the instrument station and backsight direction angle.
The coordinate values of the target are calculated using the following formula:
N1=N0+S
×
sinZ
×
cosAz
E1=E0+S
×
sinZ
×
sinAz
Z1=Z0+S
×
cosZ+ih-fh
N0: Station N coordinate S: Slope distance
ih:Instrument height
E0: Station E coordinate Z: Zenith angle
fh:Target height
Z0: Station Z coordinate
Az: Direction angle
Please get confirmation again before measuring:
