8.6.1.15 Scan time (2.1.15.)
Shows the elapsed time, in seconds, since the point displayed was last scanned.
Index Level
Values Range: 0.000 ... 9999 (Read only)
Related Sensor mode (2.1.3.) (Page 163)
This may be viewed as an Auxiliary Reading in the RUN mode.
8.6.1.16 Shot delay (2.1.16.)
Adjusts the delay (in seconds) between transducer shots.
Index Transducer
Values Range: 0.1 ... 4.0
Preset: 0.5
Use this if transient acoustic noise within the vessel is causing measurement difficulties due
to echoes from one shot being received on the next. If more than one ultrasonic unit is
installed for redundancy, this value should be 0.
8.6.1.17 Shot/pulse mode (2.1.17.)
Determines what type of ultrasonic shots are fired.
Index Single-point model Dual-point model

Long confidence (3.2.11.2.) (Page 262)
• Long echo threshold (2.11.2.3.) (Page 223)
•
Short shot range (2.11.2.12.) (Page 226)
Increases the device's 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 Long confidence (3.2.11.2.) (Page 262) produced by a short shot exceeds the short Long
echo threshold (2.11.2.3.) (Page 223) and the monitored surface is always within the Short
shot range (2.11.2.12.) (Page 226).
