Introduction
General rechargeable battery internal resistance tester, abbreviated as battery internal
resistance tester, is a measuring instrument used to measure the internal resistance, voltage and
temperature of rechargeable batteries such as lead storage batteries and lithium batteries to
determine the health of the battery. It can also be used as a meter to measure the ESR
parameters of electrolytic capacitors (for reference only). This meter uses the AC 4-terminal test
method to measure the internal resistance of the battery, and can measure the correct
measurement value without being affected by the contact resistance between the test wire,
terminal and battery electrode. It also has functions such as data storage, data access, alarm,
and automatic shutdown. The whole machine is high-grade and beautiful, with wide measuring
range, high resolution, convenient operation, easy to carry, accurate, reliable, stable
performance, and strong anti-interference ability. It is an indispensable instrument for battery
production, battery installation, equipment production, equipment maintenance and other
scenarios.
General rechargeable battery internal resistance tester is controlled by a microprocessor, the
internal 16-bit ADC can accurately detect battery internal resistance, voltage and temperature. It
is characterized by measuring without stopping the UPS system, using AC low-resistance
measurement and noise reduction technology, without stopping the normal operation of the
device under test, and measuring under the running state, which greatly shortens the test time.
At the same time, it has the functions of data storage, histogram display, data upload, computer,
mobile phone, tablet and other smart devices Bluetooth connection for wireless measurement
