Voltage and Current Harmonics

This measures the total harmonic distortion rate on voltage and current, as well as
the effective value, the harmonic distortion factor, any continuous harmonic com-
ponent and harmonics up to the 50th.
First Function: VOLTAGE HARMONIC MODE
There are 52 measurement pages in this mode. Use the ◄► buttons to move
through them.
