INTRODUCTION
This Battery Internal Resistance Meter is an intelligent
instrument which can be used for battery online
measurements. It can be used to measure battery terminal
voltage and internal resistance as well as to make normal
resistance measurements. The internal resistance is
measured with the international standard AC signal
(1000Hz ± 10%) by means of four-wire method to eliminate
the impact of the resistance of the test leads on the
measured value, and the battery voltage can also be
measured by the same connection method.
It is applicable for measurements of internal resistance of
Lithium-ion, nickel-hydroxide, lithium-manganese cells or
assembled battery.
