AC/DC Measurement

For equipment that uses rectifiers and control devices, it might not be possible to accurately measure voltage or current without an AC/DC power meter. • Half-wave rectified waveforms used for dryers and fans • Full-wave rectified waveforms used for AC adapters • Cycle control waveforms used for voltage and temperature adjustment heaters • DC waveforms with superimposed ripple components

Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)
