Calibration 35
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.
