An REM measurement is a function used to measure the height to a point where a target cannot be
directly installed such as power lines, overhead cables and bridges, etc.
The height of the target is calculated using the following formula.
Ht = h

+ h

h2 = S sin

• It is possible to allocate softkeys in measurement menus to suit various applications and the ways
that different operators handle the instrument.
