  • Page 12: Explanation Of Terms

    Explanation of Terms Beam angle: The angle that sound waves spread out from the transducer. Sound waves spread out in a conical manner taking the center of the bottom surface of the transducer at the apex of the cone. Bubbling: The phenomenon where the image of the seabed is interrupted due to air bubbles caused by the ship's hull or the propeller during a voyage.

  • Page 13: Introduction

    This information is gained by using ultrasonic waves sent from the transducer that are then reflected off the sea bottom and picked up again by the transducer. The JFE-380 also has the following functions: (1) depth alarm, (2) power fail alarm, (3) output of depth data, (4) output of depth and power fail alarms.

  • Page 47: Replacing The Fuses

    6. Replacing the Fuses Use only the specified fuses, and check the cause of the fuses blowing before replacing them. Be sure to turn OFF the main power switch (to the side marked O) on the power supply (CQD-2082) before replacing the fuses. Type No.
  • Page 48 (1) Replacing Main Power Supply Fuse F1 One reason for this fuse blowing is a faulty cable attached to the power supply. Check the cables before replacing the fuse, then turn the power on. If the fuse blows again, the Power Supply (CBD-1813) may be faulty.

  • Page 56 Seabed Quality Change Rock In case of a hard seabed composed of rocks etc., its return trails long, as shown in right chart. In case of a soft seabed made of mud, seaweed, etc., they poorly reflect an ultrasonic wave to result in thin recording of the seabed with short trail.
  • Page 57 Abrupt-Sloped Seabed Sidelobe False echo A dim echo may sometimes appear along an abrupt slope of seabed, as if it were floating above the slope, when recording. In case of flat seabed, thin second return of seabed may sometimes appear, which is slightly below the actual seabed.
  • Page 58 The echo of a seabed with abrupt slope is recorded as a lone difficult to see and less discriminative, since it tends to accompany with a false echo due to the sidelobe and the inherent property of directivity. In particular, a seabed with abrupt slope and heavily rugged surface provided an echo very difficult to display on the recording.
