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.

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.
