Mechanism

Recognizing the fact that a battery can be modeled as a voltage source in series

with a resistor, our tester applies 1000 Hz, 100mA constant alternating current to the

tested batteries, then processes them procedures such as voltage sampling,

rectification, filtration, to precisely get their resistance values. The testing makes use

of four-wire clamp, effectively eliminating the measurement error caused by contact

resistance and improving the accuracy. This equipment can also transfer the

resistance and voltage data to PC and has features such as data storage and

screening batteries
