    4-13 Words Analog Bargraph The analog bargraph provides a visual indication of measurement like a traditional analog meter needle. AC coupling True RMS When measurement is taken by true r.m.s., the measurement value of input signal becomes the scales of the signal power and therefore provide more effective values than those obtained by average value detection.
