Corner & Offset
6XUYH\ &RUQHU 2IIVHW
The Corner and Offset screen is used to store a
point using a reflectorless total station for a
point that cannot be shot directly, but the
offset(s) to the point can be measured from a
reference line that can be shot.
Foresight : is the name of the point that will be
stored.
Description : is the description for the point that
will be stored.
HR: 0.000 : shows that no rod height will be used
with this routine since all shots are direct
reflectorless.
Horiz Offset : is the horizontal distance on the line from
Shot 1 to the new point. Select L if the new point falls
to the left of Shot 1, or select R if it falls to the right.
Perpendicular Offset : is the horizontal distance,
perpendicular to the reference line, from the line to the
new point (see diagram). A positive value extends away
from the total station where a negative value is closer to
the total station.
Elevation Offset : is the vertical offset from the line to the
new point. (See diagram.) A positive value will result in
a new point above the reference line and a negative
value results in a new point below the reference line.
6KRRW /LQH : will prompt you to take two shots on the horizontal
reference line.
Note: Each shot can be in any location on the reference line (Shot 1
can be to the left or the right of Shot 2), but the
Horiz Offset is always
measured from Shot 1.
