- Maximum allowable input voltage between terminals: 400 V DC
The module features a wide-bandwidth RMS measurement circuit that supports DC and AC signals from around 30 Hz up to 100 kHz without requiring external signal conditioning. With a measurement range from 5 mV to 20 V/div and 12 selectable ranges, it can capture everything from small signal details to higher voltages. Simultaneous sampling at up to 1 MS/s on both channels allows detailed waveform and RMS analysis.
The high isolation rating of up to 300 V AC/DC to ground and maximum allowable input voltage of 400 V DC between input terminals ensures safe operation even in demanding electrical environments. RMS amplitude accuracy supports precise evaluation of both DC and AC components.
