Note
A settling time is required during the automatic range switching, and the sampled value during
this time is not accurate, which will cause integral error. Therefore, in order to obtain accurate
integration results, Fluke recommends setting the channel used for integration to manual
range, and the range should cover the instantaneous voltage and current.
Harmonic
In HARMONIC mode, the user can analyze the signals in the form of a table/bar/FFT.
