XZTZ8020 Battery Internal Resistance Tester
Product Details
Ⅰ. Characteristic
Universal rechargeable battery internal resistance tester for short: battery internal resistance tester, which is used to measure the internal resistance, voltage and temperature of rechargeable batteries such as lead-acid batteries and lithium batteries to judge the health status of the battery. Meter for capacitance ESR parameters (for reference only). This instrument uses the AC 4-terminal test method to measure the internal resistance of the battery, which can measure the correct measurement value without being affected by the contact resistance between the test wire, the terminal and the battery electrode. At the same time, it also has the functions of data storage, data access, alarm, automatic shutdown and so on. The whole machine is high-grade and beautiful, wide range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability. It is an indispensable instrument for battery production, battery installation, equipment production, equipment maintenance and other scenarios.
The universal rechargeable battery internal resistance tester is controlled by a microprocessor, and the internal 16-bit ADC can accurately detect the internal resistance, voltage and temperature of the battery. Its characteristics are to measure without stopping the UPS system, using AC low resistance measurement and noise reduction technology, and do not need to stop the normal operation of the equipment under test. The measurement is carried out in the running state, which greatly shortens the test time. At the same time, it has functions such as data storage, histogram display, data uploading to computers, mobile phones, tablets and other smart devices via Bluetooth connection for wireless measurement and data viewing.
