Switch the PI54 interference filter on and off, and observe
the numeric display. If the interference symbol is not
shown when the filter is off, leave the interference filter
switched off to increase the system’s range and
performance.

Use a water-proof pen, write the sensor’s number,
configured channel number and any other pertinent
information on its label.
- A dedicated form has also been provided in the front of
the PI Operator Manual to record this information.
Note:
Do not write on the sensor! Such information may be
misunderstood when future service or replacement is performed.

- If these values vary, calibrate by adjusting the PI54
depth offset function until the measured depth under
the vessel corresponds to the PI54’s displayed depth.
- Another method of calibration is to suspend the sensor
to a measured depth of three meters under the vessel,
and then using the PI54’s depth sensor calibration
functionality. When this calibration procedure is
performed, the offset value will be reduced by two
meters.
