Tips: True RMS zero input characteristics of clamp meter

To test sine wave signal measurement, the True RMS measurement method makes less error than traditional way of average response.
The True RMS clamp meter measures the sine wave accurately, but it may display a reading between 1 and 50 when the measured signal is not being input (select the ac voltage function, the input short circuit) for the AC function. These deviation readings are normal. They do not affect the clamp meter’s accuracy of measuring AC power within the specified measurement range.
True RMS values require the input signal to reach a certain level for measurement. Therefore, the AC voltage and current ranges are specified between 2% and 100% of full range.
