waveforms are rough approximations of a sine wave. There are numerous spikes
and dips in each cycle. AKR transducers use a mathematical algorithm called
“True RMS,” which integrates the actual waveform over time. True RMS is the only
way to accurately measure distorted AC waveforms. Select AKR transducers for
nonlinear loads or in “noisy” power environments.
