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
