WARNING

Any digital AC voltmeter, AC ammeter, frequency meter, dual-display meter for current and voltage, or thermometer should not be used to measure on devices such as batteries, electric motors of electric vehicles, non-sine wave inverters in frequently starting fields, soft starters, frequency converters, or the downstream of load switches,otherwise the instrument may be burned out!

All instruments have an error margin of ±2%, so please be cautious if you are particular about this!
