Harmonics Zoom Mode
Use to scale a selected harmonic bar graph display (Figure 13) to more
easily read the harmonic information. This mode automatically scales the bar
graph display to 100%, 50%, 20%, or 10% based on the largest harmonic
value; the magnitude of the fundamental is ignored. Using
in harmonic
screens affects the display only and does not affect measurement range
control. To change measurement ranges, the display must be in waveform or
text screens.
An arrow at the top of the bar indicates that the harmonic has exceeded its
scale. The percent of harmonic and digital values are correct even when the
harmonic bar exceeds its scale.
The cursor selection displays the percent of the harmonic and its value in
digital form.
