* Crest factor <2.5 Accuracy at sine wave +1% (50Hz/60Hz, peak value shall not exceed 60A)
* In the following cases, zero will be displayed on the LCD.
At 20Ω range of Earth resistance function: 0.04Ω or less
* 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.
