11. Height measurement (REM)
REM is a function used to measure the coordinate and height to a point where a target
cannot be directly installed such as power lines, overhead cables or bridges, etc.
Here is the equation used to calculate the data presented in above figure:
Ht=H1+ S*cosα1*tgα2-S*sinα1
H2= S*cosα1*tgα2-S*sinα1
【Procedure of REM(Ht–Ground to target)】
1. Select menu item 1 when you need the height
between the target and ground.
2. Setting height of instrument and the height of
prism
3. Press F1:【Meas】to start EDM then you can
obtain the horizontal distance between the
instrument and the target. Press F4:【Enter】to
accept the measurement data
