9. Verify that the harmonic amplitude and phase angle readings displayed by the Tester
are within the minimum and maximum limits listed in Table 4-4. (Note: The Tester
will read a positive phase when the 5520A output is a negative phase because, on the
5520A, the polarity of the phase is always relative to the NORMAL channel output.)
10. Repeat the previous three steps using the settings and limits in Table 4-4.
