Handbook SEOUus Ttidata andRepeater Operation Handbook Introduction The ST50 Plus Tridata is a multifunction instrument providing comprehensive speed distance depth sea temperature and timing information The instrument can be configured to operate as a master unit or a dedicated repeater Settings such as log speed depth and temperature units are stored in permanent memory and retained even when the power source is disconnected The log function can be calibrated automatically over a measured distance or by simple entry of a calculated calibration factor The ST50 PlusTridata also incorporates a securii feature to protect instruments mounted in vulnerable areas such as the cockpit helm or mast Thank you for purchasing an Autohelm product May we take this opportunity to wish you

Calibration The ST50 Plus Tridata should not be used for navigational purposes until the speed transducer paddlewheel has been calibrated to the vessel This is a simple operation that can be carried out automatically over a measured distance or by manually entering a calibration factor i Automatic Calibration Automatic calibration should be carried out when tidal flow is at a minimum Locate an easily identified marked and measured distance on a chart and enter this distance into the instrument 4 NoteThe measured distance should ideally be between 1 and 25 NmMiles Proceed from object 1 to object 2 measured distance pressing the SPEED key at the start and finish of the run 5 and 6 The calibration factor is calculated and displayed atthe end of each run 7 Repeat the run over the measured distance intfre opposite direction Once cl QSPEED again the calibration factor will be displayed This represents the average for the two runs A further two runs can be made if required Dont forget to store the log calibration factor NoteThe log calibration range is from 025 to 200 Calibration factors outside of this range cannot be stored 4 LOG DISTANCE 5 RUN START 6 RUN END I 7 CALIBRATION FACTOR
