7. Stake out Measurement
Stake out measurement is used to stake out the required point. The difference between the
previously inputted data to the instrument (the stake out 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 displayed using
the following formulas:
Horizontal angle difference
dHA=Horizontal angle of stake out data – measured horizontal angle
Distance difference
Distance Displayed item
SD: S-O SD=measured slope distance – slope distance of stake out data
HD: S-O HD=measured horizontal distance – horizontal distance of stake out data
VD: S-O VD=measured height difference – height difference of stake out data
NOTE:
◆ Stake out 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 Stake out
The point to be found based on the horizontal angle from the reference direction and the
distance from the instrument station.
