DSP MODE
(display mode, A key),
and then rotate the knob until
SWP + IMP
(sweep plus impedance) is displayed.

Press
SWP TIME

Place the probe in a defect-free area of the calibration standard near the 60 % wall-
loss flaw, and then press the NULL foot switch.

Slowly scan the tube.
The scan result should be similar to that shown in Figure 5-239 on page 292. The

The larger indications (full screen) represent the 40 % and 60 % wall-loss flaws.
The center (very small) indication represents the thru-wall hole.
