The U sub-menu is available only for three-phase connections, when the voltage
ratios of phases 1, 2, and 3 are equal. This sub-menu displays the harmonics of
the phase-to-phase voltage.

1
The horizontal axis indicates the orders of the harmonics (odd marking). Display of the
level of the harmonics as a percentage of the fundamental (order 1)

- DC: DC component
- 1 to 25: harmonics of order 1 to 25; when the cursor exceeds order 25, order 26 to 50
appears
- Uh 03: harmonic number
- %: ratio of the harmonic to the fundamental
3
- V: RMS voltage of the harmonic in question
- +000°: phase shift with respect to the fundamental (order 1)
