[CA] DS400 water temperature

[Chuck - Raymarine - Moderator]

Mike,

Please click here to view a FAQ addressing this subject. The reported issue may be a fault within the transducer's thermistor (most likely) or within the DS400X itself. The FAQ found here may be used to view the expected thermistor resistance at across a range of temperature. Should the measured resistance correspond to a temperature which is ten or more degrees from the actual temperature, then the transducer should be replaced. Should Gemeco, Inc. (Airmar’s US distributor (803 693 0777)) be provided with the information printed on the tag affixed to the plug end of the transducer's cable, then may provide a copy of the transducer's schematic to assist in measuring thermistor resistance. Should no fault be found with the transducer's thermistor, then it would be necessary to live with or replace the display, as Raymarine's Product Repair Center can no longer serviced DS400X/500X/600X fishfinders. The currently installed transducer may be adapted for use with an Axiom DV MFD or Axiom RV MFD.
