3.2.1 True RMS Zero Input Characteristic
• For measuring non-sinusoidal wave signal, uses true RMS measuring
method, which has less error than traditional average response measuring
method.
• The true RMS meter can accurately measure non-sinusoidal wave signal,
but if it is in AC function mode, when there is no signal to be measured (input
terminal short circuit in AC voltage mode), clamp meter may show a reading
from 1 to 50. These deviating readings are normal. In the designated measu-
rement range, they will not affect the accuracy for multimeter measuring AC.
• The true RMS can be measured only when input signal reaches a certain
level. Therefore, the measuring range of AC voltage and current should be
specified at 2% ~ 100% of full range.
