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 H F 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 M
