P806 Echo Strength
Displays the strength (in dB above 1 μV rms) of the echo which was selected as the
measurement echo.
P807 Noise
Displays the average and peak ambient noise (in dB above 1 μV rms) being processed.
The noise level is a combination of transient acoustic noise and electrical noise (induced
into the transducer cable or receiving circuitry). See
Noise Problems in the
Troubleshooting Section on page 99.
