  • Page 39: Transducer Data Setting

    How to set transducer data in MANUAL setting menu All transducers supplied by FURUNO and some transducers of other maker are listed on XDCR TYPE menu. MANUAL setting is used only when the transducer type is not listed on the XDCR TYPE menu, since the maximum transmission rate is 600 PPM in comparison with that is 750 PPM on the XDCR TYPE menu.
  • Page 40 Basically the transducer, whose output power is over 3 kW and not listed on the XDCR TYPE menu, is not allowed to connect to the FCV-1200L because of the maximum output power of internal transmission circuit of the FCV-1200L is 3 kW.

  • Page 41: Testing Transducer

    7. TESTING TRANSDUCER The transducers are classified into electrostriction type and magnetrostriction type. Generally the transducer elements of the electrostriction type are made of barium titanate, and the magnetrostriction types are made of ferrite. Those are shown with the alfa-numeric after frequency number of the transducer type, For example; 50B - 6: "50"...
