Instrument Adjustment and Calibration
The section describes the instrument adjustments and calibration routines, adjustments for Laser
Pointer (see
), for Optical Plummet (see
), and for
Tribrach Circular Level (see
Tribrach Circular Level, page 79
).
These adjustments and calibrations will change over time, the most common changes being caused by:
l
Wear and tear with use
l
Bumps and knocks during transit
l
Large changes in operating temperature
Spectra Geospatial recommends that a collimation and calibration check be carried out routinely as
follows:
l
After any long uncontrolled transport of the instrument (e.g., after service or shipment to a new
location)
l
After any accidental knock or drop
l
At any time when the operating temperature changes by more than 10 °C (18 °F)
l
At any time when the instrument changes it's height above sea level by more than 500 m (1640 ft)
