Backsight Setup
Survey Backsight Setup.
The Backsight Setup screen allows you to define your backsight prior
to performing data collection or stakeout. The screen is also
accessible from any screen that requires a backsight.
Note: all the information in the Backsight Setup screen is saved and
will automatically be recalled if the job is reopened at a later time,
but the screen must still be re-solved before you can begin surveying.
Occupy Point: is the name of the point from the current
job that the total station is occupying.
HI: is the height that the total station is above the
ground.
HR: is the distance that the backsight prism is above the
ground.
: opens the Smart Target options (Page R-444).
BS Point / BS Direction : is the point or direction of
the backsight where the total station is aiming.
Fixed Backsight: should be checked when a separate
prism is set up over the backsight. The rod height
entered here is then used independently of the foresight
rod height when checking the backsight by distance and
when shooting the backsight during repetition shots.
Backsight Circle: displays the backsight circle value, which is set
using the Circle… button, described below.
Note: The backsight circle angle is subtracted from all horizontal
angles that are read during data collection and the resulting points
are adjusted accordingly. This is usually only done when surveying
in true azimuths. This value can be change from the Backsight Circle
or Backsight Solved screens.
