1. LEVEL Sets the percentage level of the harmonic relative to the fundamental. Each
level is associated with a harmonic number. To change levels, the test state
must be off and user class must be selected.
2. HARM NO Selecting a harmonic number using the shuttle knob will allow examination of
the LEVEL and PHASE of each harmonic and changing the level and phase
angle when USER class is selected.
3. PHASE Sets the phase angle of the harmonics relative to the fundamental. To change
phase, the test state must be off and user class must be selected.
4. PAUSE Sets the pause time in seconds between harmonics tests. There is only one
value for the entire test. The PAUSE value can be changed when the test is not
running.
