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.
%DFNVLJKW : accesses the Backsight Setup screen (Page R-
78) where the current backsight can be modified.
