Speed Calibration - Raytheon ST60 Owner's Handbook Manual

Chapter 4: Calibration

Speed calibration

The speed calibration procedure involves carrying out two runs over a
measured distance, to enable a calibration factor to be determined and
applied to your ST60 Tridata instrument, to ensure optimum accuracy.
Each calibration run comprises outward and return legs, to minimise
the affect of tidal drift when the calibration factor is determined.
