Note(
) If this unit directly measures an inverter output of cycle control, SCR phase angle control or PWM control,
an error may increase due to its operation principle.
As for harmonic 5th conversion effective value and nth harmonic effective value, a display will be zero by
0.2％ or less of the measurement range. And, analog output constitutes lower limit output.
At this time, a distortion factor, harmonic 5th conversion content rate, and nth harmonic content also become
0％ (analog output is lower limit output). As for a distortion factor, harmonic 5th conversion effective
value / content, and nth harmonic effective value / content, fundamental wave effective value constitutes
zero by 3％ or less of the measurement range.
Note(
19
) Analog output and pulse output are options.
The analog output of harmonic distortion factor and harmonic content is with respect to the current 0 to 100％
and voltage 0 to 20％, will be the upper limit output from the lower limit.

Note(
) At the case of one side swing setting of bar graph. Digital meter measures reverse power to -15％ full
scale. (Instantaneous power)

Note(
) Active power, reactive power display digit.
A full scale display is below 4000：4 digits display. A full scale display is 4000 or more：3 digits display.
