Harmonic Measurement Specifications
Measurement method Calculates the AC component (peak to peak [peak width]) as a proportion of the voltage
DC component.
Effective measuring range As per voltage and voltage waveform peak value effective measurement ranges.
Display range 0.00[%] to 500.00[%]
Polarity None
Over-range display Displays [o.r] when displaying [o.r] for the voltage waveform peak value and when the
voltage is [o.r] or 0.
Invalid data display Urfsum is displayed as [- - - - -].
Measurement method Calculates the AC component (peak to peak [peak width]) as a proportion of the current
DC component.
Effective measuring range As per current and current waveform peak value effective measurement ranges.
Display range 0.00[%] to 500.00[%]
Polarity None
Over-range display Displays [o.r] when displaying [o.r] for the current waveform peak value and when the
current is [o.r] or 0.
Invalid data display Irfsum is displayed as [- - - - -].
Measurement method Zero-cross simultaneous calculation method (separate windows by channel according
to the wiring mode)
Uniform thinning between zero-cross events after processing with a digital antialiasing
filter
Interpolation calculations (Lagrange interpolation)
When the synchronization frequency falls within the 45 Hz to 66 Hz range
IEC 61000-4-7:2002 compliant
Gaps and overlaps may occur if the measurement frequency is not 50 Hz or 60 Hz.
When the synchronization frequency falls outside the 45 Hz to 66 Hz range
No gaps or overlap will occur.
Synchronization source Conforms to synchronization source (SYNC) for the basic measurement specifications.
