so, current acquisition data will be lost and the acquisition will have to
be started over.
Click the

side tab, and then the
PrPD
tab.
From the channel area, inspect all five channels to visualise PrPD
patterns (AE1, AE2, AE3, AE4 and PD).
If no pattern of interest can be found
, it is recommended to move the AE-150
to another location, either on the same tank wall or on another wall, and retry a
PrPD acquisition. If applicable: Try with the HFCT clamp installed on a different
ground cable. Follow the
Installation
and
Operation
sections of this manual to
avoid skipping any step.
If pattern(s) of interest is (are) found:
Single or multiple patterns of interest can
be found from a single PrPD acquisition. Each pattern can then be isolated using
the trigger window in order to determine if acoustic signals are related to a
particular pattern. For most cases, it is recommended to set a trigger window on
the PD channel since this channel allows more precise localization and easier
mechanical noise discrimination. Go to next step.
