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.
3.9 SEA TEMPERATURE CALIBRATION
If a suitable temperature sensor is fitted, the Hydra 2000 will
monitor the current sea temperature. The paddle-wheel has a
sensor incorporated within it, 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 a 1, we need to change it to a 2.

(1) Select SEA TEMP C on upper half on FFD Display.
