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
