3.2.1
True rms zero input
3.2.1.1 The measurement of sine wave signal, the use of true RMS measurement method than
the traditional average response method error is small.
3.2.1.2 True RMS The instrument can accurately measure the sine wave signal, but if it
is on the AC function, the instrument may display 1 to 50 if the measured signal is not
input (shorted at the AC voltage range and the input terminal) Word between a reading.
These deviations are normal. Within the specified measuring range, they do not affect
the accuracy of the multimeter to measure alternating current.
3.2.1.3 True RMS requires that the input signal reach a certain level for measurement.
Therefore, the AC voltage and current range is specified between 2% and 100% of full
scale.
