VC480C+ microohm (low resistance) tester, adopts four-wire measurement, which effectively subtracts the line resistance of the test line itself to ensure the measurement accuracy. It can test the short-wave nvis antenna resistance test, the voltage equalization ring welding of the building curtain wall lightning protection device, the reliability test of the high-voltage wire erection, the heating components, the wire resistance and the conductor connection resistance of various trains, EMUs and equipment.
