Industrial environments requires TRUE RMS measuring instruments!

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 so-called averaging measuring 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.
