24. ROUTE SURVEYING
This mode allows a variety of route surveying options widely used in civil
engineering measurement. Each menu allows the operator to initiate a string of
successive configuration/calculation/record/setting-out operations.
• The orientation of the instrument station and backsight station can be set as
necessary.
For backsight station settings, see"12.1 Entering Instrument Station
Data and Azimuth Angle".
• EDM settings can be set in the Route Surveying menu.
"31.2 EDM Settings"
• The point names and codes set when measurement results were recorded can
only be used in the Route Surveying menu.
• The Z-axis coordinate value in all Route Surveying work is always "Null" ("Null"
is not the same as "0").
