RC3563 battery internal resistance tester, true four-wire AC internal resistance sorter Lead-acid lithium battery UPS test.It supports serial ports and computer software. The battery internal resistance tester can measure the internal resistance and of the battery at the same time. It adopts a Kelvin four-wire test clip, which can better avoid the influence of contact resistance and wire resistance, and can more accurate measurements. This product adopts intelligent control, LCD display, and implanted Kalman filter mathematical algorithm. It has the advantages of high precision, high efficiency, low cost, light weight, energy saving and environmental protection. Built-in 1000mAh lithium battery, 5V charging, Android mobile phone charger can be used, convenient. This product is widely used in various battery production, maintenance, testing, scientific research laboratories and other occasions. It can also be used to measure the AC resistance of capacitors and low-resistance high-precision resistance.
