P801 Range Extension
Use this feature if an incorrect level is reported (when material level is lower than
Empty, P006).
Range Extension is the distance in Units (P005) or % of Span (P007) beyond
Empty, which is still ultrasonically measurable.
If Empty is substantially higher than the actual clarifier bottom, increase Range
Extension such that Empty plus Range Extension is greater than the transducer to
clarifier bottom distance.
Values:
P804 Confidence Threshold
Use this feature when an incorrect material level is reported.
The Confidence Thresholds are preset to 10 and 5 respectively. If the Echo
Confidence (P805) of a particular echo exceeds the Confidence Threshold, that
echo is considered for evaluation by Sonic Intelligence ™.
Values:
P805 (V) Echo Confidence
Use this feature to monitor the effect of transducer aiming, location, and
mechanical transducer / mounting isolation.
This is the value displayed when
Echo Confidence is displayed as:
"E" is displayed if the transducer cable is open or short circuited.
Values:
P806 (V) Echo Strength
Use this feature to view the strength (in dB above 1 µV rms) of the echo selected
to base the distance calculation upon.
Values:
P807 (V) Noise
Observe 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 itself).
