3. Place the probe in the hole with EDM notches, and then adjust the index axis so
that the probe rotates freely next to a defect area.

4. Turn on the scanner motor, and then press the MAIN FILTER menu key ( )

5. Press the MAIN FILTER menu key ( ), and then change the FILT TYP (C key)

Figure 6 filter setting unless an absolute probe is being used, in which case the
Figure 8 filter setting might provide better performance. For more information about
the Figure 6 versus Figure 8 parameters, see “Inspecting Fastener Holes with a
Rotating Scanner — NORTEC 600S and NORTEC 600D Models” on page 126.
