7. Before applying couplant and putting the transducer on the pipe, wait for the waveform to stabilize (about
2...4 seconds).
If measuring pipe with wall thickness greater than about 0.1” or 2.5 mm:
8. Next, Press Remove from Pipe and Clean Transducer… check box. A check should appear in the check box and the
Red-Rpk line in the waveform display will stop moving. This locks the “reference”.
