However, if a fault arises with the ST50 Plus Tridata, the following table will help to identify the probable cause and provide the most likely cure. Check cabling and security of SeaTalk connectors. Return unit for repair. , Instrument displays `CODE SET No speed or temperature information. The `Code Lock' feature Enter correct code has been set. Check cabling and security of transducer connector. Disconnect instruments one by one to isolate faulty unit. Check security of SeaTalk connectors and non-functioning units. Check cabling and security of transducer connector. Normal reading will return when clear of disturbed water. No speed information. No exchange of information between SeaTalk instruments. SeaTalk cabling problem. Failure of a group of SeaTalk instruments in SeaTalk cabling/connector chain. Depth reading flashes continuously (depth greater than 3 feet).

ST60 Pius Tridata and Repeater Operation and installation Handbook Chapter 6: Calibration The following calculation must be used when carrying out Manual Log Calibration: FKorrection Factor) = Known Distance/Vleasured Distance The Known distance is the distance between two charted objects (e. g. , two buoys). The Measured distance isthe distance recorded by the speed instrument, allowing for tidal flow. COUNTDOWN ALARM 1" 1 Approximately 1Nm Of2 w9sl To obtain the correction factor (R proceed from object 1 to object 2 and then object2 to object 1. The measured distance in each case must be noted, added together, and then divided by 2 to obtain the average distance. To obtain the correction factor, divide the known distance by the average distance. [. . . ]
