11. 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+Scosα1tgα2-Ssinα1
【Procedure of REM】
1. Set a target directly under or directly over the object
and measure the target height with a tape measure etc.
2. Press F2: [
MENU] on P2 of the basic measurement
mode, then select “
6.REM” on P1 to enter into REM
status.
3. Reference point measurement.
Aim at the prism accurately, and press F4: [
MEAS] to
measure distance. Press F4: [
STOP] and the measured
data are displayed. Press F4: [
MEAS] to re-measure.
4. Aim at the target accurately and press F2: [
REM].
The height from ground to the target is displayed in
“
Ht”. Press F4: [MEAS] to repeat and press key {ESC}
back to menu mode.
