3.4 DEPTH CALIBRATION
A typical transducer installation is through the hull at a suitable
position between the water line and the bottom of the keel. A
DATUM (offset value) can be set, such that the depth display
refers to either the water line or the keel line.
Fig 3.2 - Depth Datum
The datum is entered under:
DEPTH ? DEPTH, CALBRATE ? DATUM
3.5 SEA TEMPERATURE CALIBRATION
If a suitable temperature sensor is fitted, the HS 2000 System will
monitor the current sea temperature; the paddle-wheel has a
sensor incorporated within, in this case no further action is
required.
If the sensor is a totally independent fitting (B & G Part No. 223-
00-027) then it is necessary to change the sensor selection value.
This value is found in:
TEMP ? SEA TEMP, CALBRATE ? CAL VAL1 (SENSORS)
The default selection value is 1; this value should be set to 2.
