BK-300A Internal-Resistance-of-Battery Meter

BK-300A Internal-Resistance-of-Battery Meter is a new meter model measuring

the internal resistance and voltage of a battery using alternating current. It is

easy to use, reliable and cost-effective. The tester makes use of four-wire

clamp to eliminate the measuring error caused by contact resistance. It will

alarm when the internal resistance of the battery goes out of bounds

defined by the users.

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

with a resistor, our tester applies 1000 Hz, 20mA constant alternating current to the

tested batteries then process their procedures such as voltage sampling,

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

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

resistance and improving the accuracy.
