i50 Speed Transducer Replacement

[Chuck - Raymarine - Moderator]

Tnauck,

Speed transducers must be calibrated after mating them to an i50 Speed, i50 Tridata, or iTC-5 w/i70 MFID. The calibration procedure is specified within Section 7.4 Calibration of the i50 Instruments Installation and Operation Instructions. I50 Speed and i50 Tridata Instruments feature single point speed calibration. As the analog signal output of paddlewheel speed transducers is non-linear, the speed reported by an i50 Speed or i50 Tridata Instrument will be most accurately reported when operating the vessel at the speed that the transducer was calibrated. The i70 MFIDs feature multi-point speed calibration, allowing them to provide greater accuracy across a range of speeds.
