Note: Modifications made to the Advanced Parameters
should be performed only by or under the guidance of
trained IETG personnel. Therefore, IETG recommends
leaving the default settings (Auto) in place.
Modify the parameters as necessary, and then select OK once
complete.
 DAC Gain Choose the method for managing the
amplification of the analog signal that returns to the sensor:
− Auto Select this option to allow the monitor to
automatically optimize the amplification of the signal.
− Manual Select this option to enter a fixed value
between -12db (lower amplification) and +12db (high
amplification) at which to amplify the signal.
 Ping Amplitude Choose the method for managing the
amplification of the analog signal that is sent out, or
transmitted from, the sensor. Smaller pipes typically
require weaker (quieter) amplification; larger pipes
typically require stronger (louder) amplification.
− Auto Select this option to allow the monitor to
automatically optimize the amplification of the signal.
