Industrial environments require TRUE RMS measurements!

Non-linear loads arising, e.g. from motor drives with adjustable speed, frequency converters or mains supply units for office equipment, and LED lamps generate a reactive power in the mains. As a result, multimeters and current clamps working with the averaging measurement method ("RMS") will display the measured values with reduced accuracy.

In many cases, and particularly in industrial environments, it is therefore absolutely necessary to use state-of-the-art "TRUE RMS" measuring instruments. The "TRUE RMS" measuring method indicates the actual effective value of an alternating current correctly – irrespective of whether the signal waveform of the current is sinusoidal or distorted.
