High Accuracy Voltage and Internal Resistance Tester of Battery Cells R203

High Accuracy Voltage and Internal Resistance Tester of Battery Cells R203 R203 Internal Resistance Tester — The voltage range is 30V, with a minimum resolution of 0.001V (1mV); The internal resistance range is 2000mΩ, with a minimum resolution of 0.1mΩ. The internal resistance tester can simultaneously detect the voltage and internal resistance of various types of battery cells; accurately display specific values; Direct switching between test modes; and can set upper and lower limits for voltage and internal resistance, with audible alarm prompts. Description: Usually the smaller the resistance of a battery or cell, the better its performance. Therefore, testing the internal resistance to determine the quality of batteries and cells is a quick and reliable method. This instrument has an input impedance greater than 100K and adopts a four-wire collection method; it can test the resistance of objects with or without power supply. It has a large range, high accuracy, and simple operation, making it widely applicable to various battery and cell manufacturers; it is also very suitable for battery distributors and end users to conduct incoming inspections of batteries or cells. Features: AC signal, four-wire testing. 1.The instrument has fast testing speed, with results available in as fast as 0.1 seconds and audible alarm prompts; 2.The voltage digital display is four digits (with voltage displayed to three decimal places, 0.001V resolution, 1mV), and the internal resistance minimum display is to one decimal place, with a resolution of 0.1 mΩ; 3.Audible alarm prompts can be set for voltage and internal resistance ranges (voltage range can be set to three decimal places); 4.Test sampling frequency can be set; forward and reverse tests can be set, and the brightness of the digital display can be adjusted. 5.The instrument can be calibrated without opening the case; 6.The instrument can be upgraded for computer connectivity: (test results can be uploaded to a computer); (optional); 7.Can add external trigger I/O port signal output function; (optional).
