Depth calibration

This function is used to enable calibration of the PI54 Depth

sensor.

To access this function, press the MENU button to open the

main menu. Then, open the Setup menu, and select Sensor

alarm/calibration .

When the d ialogue opens, press the GAIN+ button a few times

to open the Depth calibration dialogue.

The Depth calibration feature will calibrate the current depth

of the Depth sensor to one -1- meter.

1 Lower the sensor over the side to a depth of one meter, to

a certain draft depth plus one meter, or to any reference

level that you wish to be defined as one meter.

2 Once the reading from the sensor is stable, set Depth

sensor calibration to YES.

The calibration takes one minute. While the process is running,

the numerical presentation is shown with grey text. Note that the

sensor must be submerged into salt water to perform the

calibration.
