6.7 Harmonics Display

Harmonic RMS value and distortion ratio can be displayed.
● Measurement items
Note 1: Even when the RMS value of voltage harmonics is set to phase to phase voltage display, it is displayed in phase to neutral voltage.
Note 2: When a fundamental harmonic is 0, the distortion ratio display 0%.
● Degree change method
When + and – are pressed, harmonic degrees change. When
