The AT520C is designed for voltage and internal resistance testing of high voltage batteries with a built-in DC high voltage meter. The AT520C can test battery internal resistance from 0.1m? to 300? and can test battery voltages up to 400V.
AT520C is new designed high voltage battery internal resistance meter, which build-in DC high voltage meter.
Resistance test range from 0.1m? to 300?, voltage range can reach to 400V.
Suitable for all kinds of high voltage battery test, such as high voltage and internal resistance of Li-battery.
