ScanStation P40/P30, Setting Up the Instrument

Setup Over a Benchmark with the Internal Laser Plummet

This topic describes an instrument setup over a marked ground point using the laser
plummet. Geo-referencing of the Leica ScanStation P40/P30 is established by setting
up over a known or assumed control point, with optional reference target measure-
ment to set the azimuth direction, and establishing a local or global coordinate
system.
The Leica ScanStation P40/P30 allows you to traverse, resect or free-station. Known
azimuth or known backsight measurements can be observed.
It is always possible to set up the instrument without the need for a marked ground
point.
With the dual-axis compensator enabled, the data scanned with ScanStation P40/P30
is corrected automatically.
About the plummet:
• The laser plummet described in this topic is built into the vertical axis of the
instrument. It projects a red spot onto the ground, making it much easier to
centre the instrument.
• The laser plummet cannot be used in conjunction with a tribrach equipped with
an optical plummet.
