[QUOTE="Δημήτρης Δ., post: 1056607900, member: 452"] Δεν μετράνε τα συνήθη πολύμετρα True RMS. Αντιγράφω απο το manual του Fluke [I]Most meters in use today have average-responding ac converters rather than true-rms ac converters like the 8060A. Usually the gain in averageresponding meters is adjusted so that the reading gives the rms value, provided the input signal is a harmonic-free sinusoid. However, if the signal is not sinusoidal, the average-responding meter does not give correct rms readings. The 8060A ac converter actually calculates the rms value through analog computation. This means that 8060A readings are accurate rms values not only for harmonic-free sinusoids, but also for mixed frequencies, modulated signals, square waves, sawtooths, 10%-duty-cycle rectangular pulses, etc.[/I] [/QUOTE]
