DMM for inverter output voltage measurement
QWhich DMM do you recommend to measure inverter output?
The output voltage of a PWM inverter contains harmonics, in addition to the fundamental wave. On the other hand, when measuring a general inverter's output voltage, only the fundamental wave is identified.
The low-pass filter function (fc=450Hz) of the DT4281/82 is designed to cut the harmonic components.
However, please note that the noise level and environment may affect accurate measurement.
