*Crest factor  2.5 accuracy at sine wave +1% (50Hz/60Hz, peak value shall not exceed 60A)
*In the following case, ZERO will be displayed on the LCD
At 20 Ω range if Earth resistance measured is  0.04 Ω
*Auto ranging shifts to upper range when the input exceeds 105% of the selected range, and shifts to the lower
range when the input falls under 80% of the lower range.
