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
