Overview

GAOTek Milliohm with Data Hold (Battery Identity test) test is used to judge the degradation of the battery by testing the internal resistance and voltage of the battery. Test range from 0.1 mΩ to 200 Ω, 0 – 50 V DC voltages, max reading of the resistance of 3200 digits and voltage of 5000 digits. It has an optional USB interface which can be used for remote control and data acquisition and analysis makes it more suitable for assembly line tests of all kinds of batteries. Accurate open voltage can be tested out by vectorless test theory. Professional sorting function and sorting sets of the beep make it more suitable for automatic assembly line tests.
