measurement for the dividing line between Zone 0 and Zone 1.
√ At each of the remaining five distances, find a frequency for which the output
values have just become stable.
For example, at 15 cm, three different frequencies might show five "Yes" readings. If
you look back to the 17.5 cm mark, two of these frequencies were stable, but the other
was not. Take the frequency that was not stable at 17.5 cm but was stable at 15 cm as
your most reliable frequency for this distance. Now, this example has determined the
frequencies that can be used to separate Zones 5 and 4 and Zones 4 and 3. Repeat this
process for the remaining zone partitions.
