Conventional Measurements with StepDrive Motor System
This chapter describes the following instrument operational methods for the
Spectra Precision FOCUS 30 Total Station:
• When combined with the application software:
– When setting/staking out, the instrument calculates and automatically
aims towards the calculated position of the selected point.
– The instrument will automatically point towards a selected reference
target to check for instrument movement during measurements.
• Instrument software corrects the collimation / trunnion axis tilt errors in real
time.
• The StepDrive motor system are continuous and endless allowing for rapid
repeat manual pointing of the instrument with no end stops.
Note –
To obtain the correct point location with the instrument, you must aim
correctly to the target.
LockNGo Measurement
Combining the StepDrive motor capability with the image based tracking system pro-
vides the ability to carry out LockNGo measurements. LockNGo enables the instru-
ment to automatically lock on to a prism, and then follow it precisely as it moves.
This means that the instrument is taking care of the pointing, and that position can be
continuously updated as the target moves around the jobsite. LockNGo is especially
useful for carrying out rapid site topo measurements and during stakeout using a con-
ventional two person crew. It is also exceptionally useful for working in poor visibil-
ity and darkness conditions, and for automatically checking to reference targets
during measurements.
