7.2.2
C21 (Unit m)
Unit for depth. Metre (m), feet (Ft) or fathoms (FA).
7.2.3
C22 ( - 00.0 ADJ)
Calibration of the depth transducer position.
This option is used to select whether the displayed water depth is measured from the
water level or the keel.
To measure from the keel, use the minus ( - ) sign.
Example:
( - 01.2 ADJ). The distance from the transducer to the keel is 1.2 m
To measure from the water surface, use the underlining character
( _ ) sign.
Example:
( _ 00.4 ADJ). The distance from the transducer to the water surface is 0.4
m.
The selected value will be subtracted or added from the measured depth.
7.2.4
C23 (Unit°C)
Unit for temperature. Celsius (C) or Fahrenheit (F).
7.2.5
C24 (0°C TMP)
Value for compensation of the temperature.
To add, use underlining character ( _ ) ahead of the digit ( _1 TMP).
To subtract, use minus character ( - ) ahead of the digit (-1 TMP).
