Setout Measurement; Distance Setout - GPI -122 Instruction Manual

7. Setout Measurement

Setout measurement is used to Setout the required point. The difference between the
previously inputted data to the instrument（the Setout data）and the measured value can
be displayed by measuring the horizontal angle, distance or coordinates of the sighted
point.
The horizontal angle difference and distance difference are calculated and diplayed
using the following formulars:
Horizontal angle difference
dHA=Horizontal angle of Setout data – measured horizontal angle
Distance difference
Distance Displayed item
SD: S-O SD=measured slope distance – slope distance of Setout data
HD: S-O HD=measured horizontal distance – horizontal distance of Setout data
VD: S-O VD=measured height difference – height difference of Setout data
NOTE:
◆ Setout data can be input in various modes: SD, HD, VD, coordinates and REM
measurement.
◆ EDM settings could be set in this mode.

7. 1 Distance Setout

The point to be found based on the horizontal angle from the reference direction and the
distance from the instrument station.
