4. If you choose Reference Line, tap Next. Two options are
possible:
• Either you set up the instrument on the origin of the
reference line. (The origin will have been marked on
the job site.) You just have to shoot another point of
your choice, also located somewhere on the line (see
[5] and [6] below). You may measure elevations or not
(see below). Tap
Finish when it’s done.
As a result, two points are created:
point “1” (origin): N(y)= E(x)= 0
point “2”: N(y)= non-zero distance value, and E (x)= 0
• Or you set up the instrument somewhere off the
reference line and you shoot two points located on the
line (see [7] and [8] below). The first of these points
MUST be the origin of the line, the other one may be
located anywhere along the line. You may measure
elevations or not (see below). Tap
Finish when it’s done.
As in the first method, two points are created if you do
not save the instrument location:
point “1” (origin): N(y)= E(x)= 0
point “2”: N(y): non-zero distance value, and E (x)= 0
It is strongly advised to store the instrument location
as well (by enabling the
Store Instrument Location option
prompted on the screen). The resulting point will be
named “point 1”. You may add a description for the
point. In that case, the other two points will be named
respectively “2” for the origin (1st point shot), and “3”
for the 2nd point shot.
