Enhanced Low-Frequency Current Measurement Analysis Capabilities
■ Measures current from 1 Hz, such as that used for inverter motor control.
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
❍
AC+DC mode measures true rms current of full- and half-wave rectifi ed 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 fl uctuating loads
❍
Simultaneous waveform and rms output enables rms and waveform or frequency fl uctuations to be externally recorded together
❍
Selectable measurement response time enables setting the instrument response to suit changes in load current
❍
LPF (fc = 550 Hz) fi lters out unnecessary harmonic currents and noise
