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.

The datum is entered under:

3.8 BATTERY VOLTS CALIBRATION
The Hydra 2000 constantly monitors the yacht's battery supply which can be
called up on any display, giving a reading in volts. This is calibrated by the
manufacturer and should not require adjustment except in exceptional
circumstances or after a system reset.
If it is necessary to calibrate this function a suitable voltmeter is required.
The calibration value is found in the menu in:
MOTOR →→ VOLTS, CALBRATE →→ CAL VAL1
Using the independent voltmeter, measure the battery supply at terminals 18
(+) and 17 (-) at the Computer Unit connection block. CAL VAL1 is altered to
match the value from the voltmeter.
