7. Repeat procedures 4 to 6 in the same way from the second
point.
When the minimum quantity of observation data required for
the calculation is present, [CALC] is displayed.
8. Press [CALC] to automatically start calculations after
observations of all known points are completed.
Instrument station coordinate and standard deviation, which
describes the measurement accuracy, are displayed.
9. Press [RESULT] to check the result.
• Pressing {ESC} returns to the previous screen.
• Press [ADD] when there is a known point that has not been
measured or when a new known point is added.
10.If there are problems with the results of a point, align the
cursor with that point and press [OMIT]. "*" is displayed on
the left of the point. Repeat for all results that include
problems.
11. Press [RE_CALC] to perform calculation again without the
point designated in step 10. The result is displayed.
If there are no problems with the result, go to step 12.
If problems with the result occur again, perform the resection
measurement from step 4.
• Press [RE_MEAS] to measure the point designated in step
10.
If no points are designated in step 10, all the points or only
the final point can be observed again.
12.Press [OK] in the screen of step 9 to finish resection
measurement. The instrument station coordinate is set.
Press [YES] when you want to set the azimuth angle of the
