3.2 Technical Indicators

3.2.1 True RMS Zero Input Characteristic
3.2.1.1 For measuring non-sinusoidal wave signals, use the true RMS
measuring method, which has less error than the traditional
average response measuring method.
3.2.1.2 The true RMS meter can accurately measure non-sinusoidal
wave signals, but in AC function when there is no signal to be
measured, the clamp meter may show a reading from 1 to 50.
These deviating readings are normal. In the designated measure
ment range, they will not affect the meter's accuracy.
3.2.1.3 True RMS can be measured only when input signal reaches a
certain level. Therefore, measuring range of AC voltage and
current should be specified at 2%~100% of full range.
