HIOKI 3290 CLAMP ON HI TESTER

Inverter motor current and rms waveforms are recorded simultaneously. Simultaneous recording of control signals is the best method for evaluating and analyzing such devices during product development and maintenance. Features: Choice of three sensors ( Examples) 3290+ 9691 : Measure up to 100A 3290+ 9692 : Measure up to 200A 3290+ 9693 : Measure up to 2000A Choice of measurement methods DC ( for battery measurement) , AC+ DC RMS ( for full/ half-wave rectification measurement) , AC RMS ( for current distortion measurement) , PEAK ( for peak value measurement) of inrush current, etc.) Choice of output ( Simultaneous output) Effective value output, frequency output, waveform output AC+ DC mode measures true rms current of full- and half-wave rectified waveforms and inverter output waveforms from 1 Hz Peak mode measures the maximum waveform amplitude of in-rush current at device startup Maximum, Minimum and Mean value modes easily measure current variations in lines with severely fluctuating loads Simultaneous waveform and rms output enables rms and waveform or frequency fluctuations to be externally recorded together Selectable measurement response time enables setting the instrument response to suit changes in load current LPF ( fc = 550 Hz) filters out unnecessary harmonic currents and noise
