Harmonics Zoom Mode

Use rto scale a selected harmonic bar graph display (Figu e 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 rin 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.
