• -Universal rechargeable battery internal resistance tester Abbreviation: battery internal resistance tester. It is a measuring instrument used to measure the internal resistance, voltage and temperature of rechargeable batteries such as lead storage batteries and lithium batteries, and to judge the health of the batteries.
• -This meter uses the AC four-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 of the test line, terminal, and battery electrode. It 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, convenient carrying, accurate and reliable, stable performance and strong anti-interference ability. It is an indispensable instrument for battery production, battery installation, equipment production, and equipment maintenance.
• -Generally, the internal resistance tester for rechargeable batteries is controlled by a microprocessor, and the internal 16-bit ADC can accurately detect the internal resistance, voltage and temperature of the battery.
• -Its feature is that it does not stop the UPS system for measurement, adopts AC low-resistance measurement and noise reduction technology, does not stop the normal operation of the equipment under test, and performs measurement in the running state, which greatly shortens the test time.
