Item Function
Harmonic selection cursor; change values with the cursor using the ◄ and ►buttons
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)
2 - DC: DC component
- 1 to 25: harmonics of order 1 to 25; when the cursor exceeds order 25, order 26 to 50
appears
- Ah 05: harmonic number
- %: ratio of the harmonic to the fundamental
3
- A: RMS current of the harmonic in question
- +000°: phase shift with respect to the fundamental (order 1)

NOTE: Filters L2 and L3 display the current harmonics of phases 2 and 3, respectively.
The screen is identical to the one displayed for filter L1.
