2. Measure the first direction.
Collimate the first target. Press [ANGLE] or [MEAS] to start
measuring. In "D=", the setting value for the Number of
distance readings (No. of Obs) is displayed.
• Target height, point name and code can be entered before
the measurement.
• If "No" is set for (5) Backsight distance measurement (BS
Obs-Dist), [MEAS] is not displayed on the Topography
screen.
• If "Yes" is set for (6) Backsight distance check (BS
DistCheck), the variance for horizontal distance between
the calculated value and the measured value is displayed
after the measurement of the first point has been
completed.
• Pressing {ESC} cancels the topography observation after
checking is completed.
3. Record measured data.
If a target height and code have not been set, enter the data
here.
Press [OK] to save the data. The screen for step 2 is
displayed to measure the next point.
During the measurement for the second point and thereafter,
if: (1) Number of distance sets (No. of SETs) is set to "1"; (2)
Number of distance readings (No. of Obs) is set to "1"; and
(3) RL observation (F1/F2 Obs) is set to "No"; [OFFSET] is
displayed. Pressing [OFFSET] enables offset measurement
of the target point.

4. End topography observation measurement.
After completing the observation, pressing {ESC} displays
the completion confirmation message. Press [YES] to
record the topography observation.
• When the collimation point is registered, this message
does not appear.
PROCEDURE Topography RL Observation
1. Perform observation setting following procedures 1~6 in the
"19.1 Observation Setting".
Set "YES" for "RL observation" in the observation setting.
