known point, press [NEXT] to move to the second point.
7. If measuring two or more known points, repeat procedures
4 to 6 in the same way from the second point.
• Press {ESC} to return to the previous known point.
8. Press [CALC] to automatically start calculations after
observations of all known points are completed. Instrument
station elevation and standard deviation, which describes
the measurement accuracy, are displayed.
