Max/Min: Indicators of the maximum and minimum of the level of the harmonic in
2.
The horizontal axis indicates the orders of the harmonics.
(the bars of the chart that are above the horizontal axis represent harmonic power
consumed, while those below it represent harmonic power generated).
Display of the levels of the harmonics as a percentage with respect to the fundamen-
tal (order 1).
Order 0: DC component (with MR193 only)
Order (1 to 25): order of the harmonics. As soon as the cursor goes past order 25, the
range from 26 to 50 appears.
Note: The ► icon to the right of harmonic 25 indicates the presence of harmonics of
order higher than 25.
