• Deadband Select the distance from the sensor face within
which readings received will be ignored. The default value
(Auto) represents a percentage of the flow depth and should
be sufficient under normal circumstances. However, consider
another value when the sensor readings reveal a potential
problem with false drop-outs. Choose a value for the
deadband that is sufficiently below the minimum depths that
legitimately occur at the monitoring point, yet above the
confirmed drop-outs that have been detected. For example,
choosing 1 inch causes all ultrasonic depth ranges measured
within 1 inch from the face of the sensor to be ignored.
• Store Data Select this checkbox to ensure the monitor logs
the ultrasonic data to memory. This option is selected by
default.
• Advanced Select this button to access the Advanced
Parameters window.
Note: Modifications made to the Advanced Parameters
should be performed only by or under the guidance of
trained ADS personnel. Therefore, ADS recommends
leaving the default settings in place.
Advanced Parameters
 DAC Gain Choose the method for managing the
amplification of the analog signal that returns to the sensor.
Select the Auto (default) option to allow the monitor to
automatically optimize the amplification of the signal.
Choose Manual to enter a fixed value between -12dB
(lower amplification) and +12dB (higher amplification).
