6.4.6 HArM Submenu

HArM – Harmonic Analysis Parameter
In order to analyze the measuring signal's harmonics, its funda-
mental frequency must be specified wit the HARM.F parameter.
Due to the fact that the MAN key is used for another purpose in
the harmonic analysis function, it cannot be used to switch back
and forth between automatic and manual range selection. For this
reason, the U.ranGE and I.ranGE parameters are used to specify a
measuring range for harmonic analysis:
• U.Range (I.range) = auto:
Automatic range selection is used at the voltage jack (current
jack) for harmonic analysis.
• U.range (I.range)  auto: Manual range selection is enabled at the
voltage jack (current jack) for harmonic analysis, and the se-
lected range is used. The range can be changed with the left
and right scroll keys.
