4. ADJUSTMENT
4-4
DRAFT
Set ship’s draft to get depth from draft rather than transducer. (-5 – 25.0 (m))
HEEL ANGLE
Compensate lateral (port-starboard) inclination of the transducer face. Set “+” angle for
port-high state and “-” angle for starboard-high state. (-12.8 – 12.7 (°))
Set to +5.0 when port side
is higher than starboard side
by five degrees.

Starboard
θ
TRIM ANGLE
Compensate for fore-aft inclination of the transducer face. Set “+” angle for fore-high state
and “-” angle for aft-high state. (-12.8 – 12.7 (°))
Set to +5.0 when fore side
is higher than aft side by
five decrees.
θ
GT SPD CALIB
Calibrate ship’s speed in the ground tracking mode. (setting range: -12.8 – 12.7 (%)) True
speed should be calculated at the sea trial. Calibration value is obtained as follows:
Calibration value (%) =
X 100
True speed
True speed - (CI-88-measured speed)
WT SPD CALIB
Calibrate ship’s speed in the water tracking mode. In general, enter the same value as the
GT SPD CALIB. (-12.8 – 12.7 (%))
BEARING CALIB
Calibrate bearing offset angle of the transducer. When the transducer’s fore-aft axis is
deviated to starboard from the ship’s fore-aft line, set a positive angle. (-30 to 30 (°))
