What is the benefit of making voltage measurements with a true-RMS calculating meter?

Standard voltmeters are calibrated to read the Root Mean Square (RMS) voltage of a pure sine wave by simply measuring the peak voltage and multiplying it by 0.707. If the signal is a square wave, triangle wave, or heavily distorted, a standard meter will give an inaccurate reading because the 0.707 conversion factor no longer applies. A 'true-RMS' calculating meter solves this by actively sampling the waveform and mathematically calculating the actual root-mean-square value of the signal. This means it provides an accurate RMS power-equivalent reading regardless of the waveform's shape. Other options are incorrect because true-RMS meters do not measure RMS noise factor as a specific function, nor do they calculate phase angles (phasor form) or compute Fourier transforms; their sole purpose is providing accurate voltage equivalents for complex or non-sinusoidal waveforms.
