3.4 Viewing Harmonic Measured Values
71
The instrument displays the results of harmonic analysis for voltage, current, and active power.
Since all calculation processing is performed in parallel internally, you can obtain harmonic measured values
with simultaneity with other measured values simply by switching display parameters.
Additionally, when the synchronization frequency is 45 Hz to 66 Hz, the instrument can perform harmonic
measurement that compliant with IEC 61000-4-7:2002.
Set the synchronization source for the harmonic measurement to be performed with the instrument as
described in "3.2.4 Setting the Synchronization Source (SYNC)" (p.48).
The following table summarizes the instrument’s harmonic measurement parameters and corresponding dis-
play methods:
