Understand the AC zero input.
When measuring the AC voltage and current, the meter is calculating the input and converting it to
the data that the LCD can display. The converter needs a certain level of the input voltage to make
the measurement. This level is 5% of the ranges for this meter. So that, the non-zero digits that are
displayed on the meter (especially the True RMS meter) when the test leads are open or are
shorted are normal. This will not affect the specified AC accuracy above 5% of the ranges.
