Increases SITRANS LU01 response when the monitored surface is close to the
transducer face. Select short and long to have short and long acoustic shots fired for
each measurement, regardless of the transducer to surface distance. Select short to
have only short shots fired if the Echo Confidence (P805) produced by a short shot
exceeds the short Confidence Threshold (P804) and the monitored surface is always
within the Short Shot Range (P852).
P804 Confidence Threshold
Determines which echoes are evaluated by software.
The short and long shot Confidence Thresholds are preset to 10 and 5 respectively. When
Echo Confidence (P805) exceeds the Confidence Threshold, the echo is evaluated by
Sonic Intelligence. Values are entered as two numbers separated by a decimal point. The
first number is the short shot confidence and the second number is the long shot
confidence.
P805 Echo Confidence
Displays the echo confidence of the measurement echo from the last shot.
Use this feature to monitor the effect of transducer aiming, location, and mechanical
transducer / mounting isolation.
Both short and long shot Echo Confidence is displayed. (To display this value in the
auxiliary display while the unit is running, press
for 4 seconds.)
