Omron RX User Manual page 339

Note 1: For output voltage, use
a measurement device
that displays effective
values of fundamental
wave. For current and
electric power, use a
measurement device
that displays all
effective values.
Note 2: The Inverter output
waveform, under PWM
control, has a margin of
error, especially at a
low frequency.
Note 3: General-purpose
testers are not
applicable because of
noise in many cases.
