3.2 Technical Indicators
3.2.1 True RMS characteristics
3.2.1.1 For non-sinusoidal signal measurement, the
Meter provides more accurate measurement than
the traditional averaging method.
3.2.1.2 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.
3.2.1.3 True RMS requires a minimum input level, AC
current or voltage should be 2%~100% of the
maximum level.
