Using 3280 series AC clamp meters: Introduction to functionality and measurement methods

In addition to AC current measurement, these clamp meters provide voltage and resistance measurement as well as continuity check functionality.
Their compact size, low-profile design, and resistance to both rough handling and extreme temperatures make them essential tools for any electrician.

Using 3280 series AC clamp meters: Difference between mean value and true RMS measurement

Measurements taken with the Hioki 3280-10F (which uses the mean value method) and the the Hioki 3280-20F (which uses the true RMS method) are compared.
Observe the difference between readings from these two types of instruments when measuring a distorted waveform that contains harmonic components such as those produced by inverters and switching power supplies.
