9.4.1 Remote height (REM)
REM is adequate for measuring target height when the
prism cannot be placed at the target point. Under REM mode,
users may place the prism on any point along the plumb line of
the target point to obtain target height.
There are two modes for REM measurement: „with TH‟
and „without TH‟. Users may select „with TH‟ mode when
altitude from ground to target is to be measured, otherwise
„without TH‟ when altitude from any reference point to target is
to be measured.
With TH:
1. Enter the instrument height and target height firstly.
2. Press „ENT‟ to enter „REM-Prism‟
