Why choose a true rms clamp meter?

When it comes to electrical testing, accuracy is everything. Whether you're working in industrial, commercial, or residential settings, precise measurements can mean the difference between a safe, efficient system and costly electrical failures. That’s where True RMS Clamp Meters come into play. Unlike standard clamp meters, True RMS meters provide accurate readings even when measuring non-linear loads. If you’re looking for reliability and precision, Major Tech’s MT770 True RMS Clamp Meter is the perfect choice.

What is True RMS, and Why Does It Matter?

RMS (Root Mean Square) is a method used to calculate the effective voltage or current of an AC signal. Many electrical loads today—such as Variable Frequency Drives (VFDs), LED lighting, and switching power supplies—produce distorted waveforms rather than pure sine waves. Standard clamp meters assume a perfect sine wave, which can lead to incorrect readings.

True RMS meters, like the MT770, accurately measure AC signals regardless of waveform distortions, ensuring precise and reliable results. This makes them essential for modern electrical work, where electronic devices and nonlinear loads are common.
