AT520B AT520C are newly designed high voltage battery meter, which aims to measure voltage and internal resistance of battery with built-in current high voltage meter. It can test Not only 0.1mW-30W internal resistance of battery, but also max 800V battery voltage simultaneously at the same time, suitable for all kinds of high voltage battery test, such as multi-section series connection of high voltage, Li-battery and internal resistance
