Echo Processing Parameters
Transducer Status
P900 Transducer Status
This parameter shows the current state of the transducer. The value means
the following:
OPTION
DESCRIPTION
0= OK
Transducer working correctly.
1= Disabled
Transducer is not being used (mA input is being
used instead, so P101=1)
2= Stuck High
Indicates that the power and signal lines on the
transducer terminals are crossed over, or the signal
line is shorted to earth.
3= Not Found
No transducer is detected.
P901 Echo Confidence
This parameter displays the most recent echo confidence from the
transducer. It is useful to help find the best mounting location for the
transducer, where you should aim to get the highest figure. It is a
percentage of confidence that the echo reporting the level is the correct
one.
P902 Echo Strength
This parameter displays the most recent echo strength figure for the
transducer, where a higher figure indicates a better returned echo.
P903 Average Noise
This is the mean noise reading for the transducer. It is measured while the
transducer is not firing and gives an indication of the average amount of
electrical noise present on the cabling.
P904 Peak Noise
This is the peak noise reading for the transducer. It is measured while the
transducer is not firing and gives an indication of the maximum amount of
electrical noise present on the cabling.
