Speed Calibration For Conventional Speed Transducer - Raymarine ST70+ Installation Manual

48
Carry out the procedure for either Speed calibration for conventional speed
transducer or the Speed calibration for smart transducer, as appropriate for your
vessel.

Speed calibration for conventional speed transducer

When calibrating a conventional Speed transducer, you can obtain correct values for
the calibration factor by one of two methods:
• If SOG information is available, you can use this as a reference, to enable you to
set the correct calibration factor.
• If SOG information is not available, you need to manually calculate and apply the
correct calibration factor.
Carry out the Starting speed calibration procedure (below) followed by either:
• the Set to SOG procedure (page 49), or
• the Manual speed calibration procedure (page 49)
as required.
