Internal Resistance Tester - TR1035

Digital YR1035 Lithium Battery Internal Resistance/Impedance Tester Test the Voltage and AC impedance of any battery type. This handheld Internal Resistance Battery Tester can determine the AC impedence of your battery cells. It is very useful for when you'd like to get match cells in a string. It also functions as a voltage meter. The machine does not have a charger, charging can be charged with an Android phone charger. The length of the test line is 0.5 meters. Specifications Range minimum resolution accuracy 20mΩ 0.01mΩ 0.7%+7 200mΩ 0.1mΩ 0.5%+5 2Ω 1mΩ 0.5%+5 20Ω 10mΩ 0.5%+5 200Ω 0.1Ω 0.6%+5 In the range of 5%-95% of the gear position, if it is not within this range (less than 5% gear range range, or greater than 95% gear range range), the error may be greater than the above accuracy.
