Adjustment
Leveling Adjustment .
The Adjustment routine allows you to perform a simple arithmetic
elevation error adjustment to an existing closed loop. You can choose
to distribute the error equally to each setup, or apply a weighted
adjustment proportional to the distance between each setup. You
also have the option to adjust any side shots that were performed in
the selected loop.
Weigh by # of Setups: This option divides the
computed error equally among each setup selected in the
loop.
Weigh by Length of Setups: This option distributes the
error where each setup is adjusted by an error
proportional to the length between them, so setups that
are farther apart will carry a larger portion of the error
adjustment than the setups that are closer together.
Adjust Affected Sideshot Points: When checked, any
side shots will be adjusted by the same amount as the
setup that was occupied when the side shots were
performed.
Adjust Loop From Begin To End: This option includes
every setup of the selected level loop in the error
adjustment.
Adjust Loop From a Specific Point To End: This option will only
adjust the setups starting from an alternative benchmark specified in
the Begin CBM Pt field to the end of the loop.
Closed Loop Name: is where you select the loop to adjust from the
dropdown list. Only closed loops are available.
Begin CBM Pt: This item is only available when Adjust Loop From a
Specific Point To End is selected above and allows you to select an
alternative benchmark starting point in the loop for the adjustment.
Any setups prior to the selected benchmark will not be adjusted. The
description and elevation for the selected benchmark are displayed at
the bottom of the screen.
