R-79
Current BS Direction : displays the azimuth of the current backsight.
&KHFN« : accesses the Check Backsight dialog box (Page R-79),
which is used to help confirm that the total station is facing the
correct backsight.
&LUFOH« : accesses the Backsight Circle dialog box (Page R-80) where
the backsight circle can be changed, or the circle reading on the total
station can be set remotely.
6ROYH : solves the screen based on the information entered and
automatically displays the map view showing the location and
direction of the current backsight.
Check Backsight Dialog Box
The Check Backsight screen is used to help confirm that the total
station is facing the correct backsight by comparing the known
distance or circular angle to the backsight with the measured value.
%\ 'LVWDQFH : will take a shot to a prism located over the backsight
point and compare the measured distance with the computed distance
between the occupy and backsight points stored in the current job.
Note: The Check by Distance method does not apply if
the backsight is defined by a direction.
%\ $QJOH : when the backsight is defined by a direction,
this routine will read the current horizontal angle from
the total station and compare that to the backsight
direction.
&LUFOH« : accesses the Backsight Circle dialog box,
described below.
