Frequently Asked Questions (FAQ)
-
What is True-RMS and why is it important?
True-RMS (Root Mean Square) is a measurement technique that accurately calculates the effective value of an AC voltage or current waveform, even if it’s non-sinusoidal. Non-linear loads like variable frequency drives and electronic ballasts create distorted waveforms. Average-responding multimeters can provide inaccurate readings with these waveforms, leading to misdiagnosis and potential safety hazards. The Fluke 87V’s True-RMS capability ensures accurate measurements in these situations.
-
What are CAT ratings and why do they matter?
CAT (Category) ratings indicate the level of protection a multimeter provides against voltage transients or spikes. Higher CAT ratings offer greater protection. The Fluke 87V has a CAT III 1000V and CAT IV 600V rating, making it suitable for use on various electrical systems, from household circuits to industrial power distribution.
