Fluke 434/435

Users Manual

Harmonics	Measurement Range			Resolution	Accuracy
Harmonic order (n)	DC, 1..50		Grouping: Harmonic groups according to IEC 61000-4-7
Inter-Harmonic order	Off, 1..49		Grouping: Harmonic and Interharmonic subgroups according to IEC
	61000-4-7
Filtering	When measuring harmonics with interharmonics off, harmonics group is used
	and a 1.5 s smoothing filter is active.
	When measuring harmonics with interharmonics on, harmonics subgroup and
	interharmonics centered subgroup are used and no filter is active.
