Brief Introduction

The measurement of contact resistance of switches in power systems is one of the important contents of electrical testing. The SN2600 series loop resistance tester, produced in accordance with the standards of GB763-74 and IEE694-84, adopts highly integrated SMD components, unique constant current source technology, and single-chip intelligent control, greatly improving system stability and reliability. It has the characteristics of high testing accuracy, strong anti-interference ability, simple operation, stable display, and truly portable. It is suitable for precise measurement of micro-ohm values of high-voltage switches, combined electrical contacts, busbars, and other electrical equipment. It can conveniently measure contact resistance and current-carrying conductors of contacts, circuit breakers, switches, and other equipment, and can also be used alone as a DC high-current source for a short time.
