3.2 Technical Specifications
3.2.1 True RMS Characteristics
• For non-sinusoidal signal measurement,the Meter
provides more accurate measurement than the
traditional averaging method.
• If in AC current mode,the Meter may display a random
reading between 1 and 50 when the input is not active.
This will not affect the accuracy of measurement.
• True RMS requires a minimum input level,AC current
or voltage should be 2%~100%of the maximum level.
