26. CROSS SECTION SURVEY
Enter center point name. Then press
[OK]
.
• When the center point is set as the instrument station,
press
[LOAD]
to read in already registered coordinate data
and set as the coordinates of the instrument station.

9. Repeat steps 5 to 6 for all points on the cross-section
occurring after the centerline.
10.After observing the last changing point, check that "Finished
section" is set to "Yes", then press
[OK]
.
• Observation can be cancelled by pressing
{ESC}
. In this
event, a confirmation message window is displayed. Press
[YES]
to discard measurement data observed up to that
point and exit observation. Press
[NO]
to continue
observation.
11.Proceed to observation of the next cross-section.
• Road name: up to 16 characters
• Sta incr: -999999.999 to 999999.999 (m)
• Sta..ing: -99999.99999 to 99999.99999 (m)
• Sta pitch: 0.000 to 999999.999 (m)
• Direction: Left->Right/Right->Left/Left/Right
Direction
Cross-sections can be measured in the following directions depending on the setting selected in
"Direction".
When "Left" or "Left -> Right" selected
Pattern 1: From left-most point to right-most point.
Pattern 2: Center point observed first. Then the point immediately to the left of the center point. Remaining
points can then be observed in any order.
Pattern 3: Method using 2 prisms. Center point observed first followed by the point immediately to the left.
Subsequent observations can be in whatever order is the most efficient for operation with 2
prisms. In the illustration below the points closest to the center point are observed first, followed
by the outermost points (left first, then right).
