25.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
"13.1 Entering Instrument Station Data and Azimuth Angle".
• EDM settings can be set in the Route Surveying menu.
"33.2 Observation Conditions - Dist"
• 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").
