24.TRAVERSE ADJUSTMENT
Measurement of a traverse begins with observation of the backsight station and foresight station. The
instrument station is then moved to the foresight station and the previous instrument station becomes the
backsight station. Observation is performed again at the new position. This process is repeated for the length
of the route.
This adjustment function is used to calculate the coordinates of such a sequence of consecutively-observed
points (traverse points and points observed from traverse points (see P3-1 to P3-3 below)). When calculation
is complete, the iM displays the precision of the traverse and, when necessary, traverse adjustment can be
performed.
For types of traverse that can be calculated with the iM, see "Types of traverse"
Backsight Station
PROCEDURE
1. Before starting traverse calculation, observe the sequence
of traverse points and record the results.
"28.4 Recording Distance Measurement Data"/
"28.6 Recording Distance and Coordinate Data"
2. In the second page of the OBS mode screen, press
[MENU], then select "Traverse".
3. Enter the start point name and press {ENT}.
• When [LIST] is pressed, a list of instrument stations saved
in the current JOB is displayed. A point from this list can be
recalled and used.
