SOUNDING FOR LEAK NOISE
Once the transducer is properly positioned on the access point,
turn the S30 on. Use the VOLUME CONTROL to set the S30 to
a comfortable level for your ears. At this time the operator must
determine two things:
1.
Do you hear leak sound?
2.
What is the intensity of that leak sound?
If leak sound is monitored, note the location and relative signal
level for reference.
When this has been completed the operator advances to the
next access point. The operator uses the intensity of the leak
sounds to determine the approximate location of the leak. The
stronger or greater the leak sound intensity, the closer to the
leak.
