P803 SHOT/PULSE MODE
Use this feature to increase response independent from Measurement Response (P003).
Select "short and long" to have short and long acoustic shots fired each time a vessel is
scanned. Select "short" to have only short shots fired if the Echo Confidence (P805) produced
by a short shot exceeds the short Confidence Threshold (P804).
This value is automatically altered when Measurement Response (P003) is altered. See
Measurement Response.
values: 1 = short
2 = short and long
P804 CONFIDENCE THRESHOLD
Use this feature when an incorrect material level is reported.
The short and long 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
TM
.
values: x.y x = short (0 to 99), y = long (0 to 99)
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 is pressed for 4 seconds in the RUN mode.
Both short and long shot Echo Confidence is displayed.
"--" is displayed if the respective shot (short or long) was not included in the evaluation.
"E" is displayed if the transducer cable is open or short circuited.
"--:-- is displayed if no shots have been taken yet.
values: x:y x = short (0 to 99), y = long (0 to 99)
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: 0 to 99
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).
values: x.y x = average (-99 to 99), y = peak (-99 to 99)
