1. Do not clamp the current probe around any conductor, but make sure the
jaws are locked shut.
2. Press the amplifier PROBE DEGAUSS AUTOBALANCE button. Wait for
the degauss/autobalance routine to complete before proceeding. The routine
is complete when the indicator light turns green.
3. Clamp the current probe around the HF current loop.
4. Enable the output of the leveled sinewave generator.
5. Verify the output level is what is listed for the probe in Table 5--16.
6. Using the peak-peak measurement capability of the oscilloscope, measure
the peak-peak reading and record it in Table 5--16 as
