• 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
• Polarity-specific integral function measures battery charging and discharging with one instrument (positive, negative and total integral values)
• Operating time/Rate display function measures load operating status (with settable threshold value)
• Polarity-specific peak current display function measures peak battery charge and discharge current with one instrument
• Repeat measurement and data storage function lets you easily conduct the same measurement up to 20 times and then save that data in the unit's memory.
• Time-limited mean value display function shows the mean value within a specific integration time (can be used in combination with repeat measurement)
