Most multimeters, when used for AC measurements, do in fact read RMS values. Specialized meters do exist which will read peak (or average, or whatever), but the common meters do read RMS only. If you measure your household AC voltage (in the US) with your meter, and you find a reading somewhere about 115 or 120 volts, you can be assured that the meter is displaying RMS values. ----------------------------------------------------------------- The only thing to be careful with some DMM are that whilst they will measure RMS voltage at AC power frequencies, will be inaccurate at frequencies in the kHz range. A early Tandy (Radio Shack) DMM I purchased was wildly inaccurate when trying to measure audio frequencies whilst checking large audio PA systems, where the 8000 series Fluke was perfectly OK in measuring audio up to at least up to 5kHz.
