Detail
Portable micro-ohmmeter is also called DC low resistance meter, DC resistance tester, ohmmeter. The instrument adopts microprocessor technology and four-wire method test, which is safe, precise and reliable. It is mainly used to measure the wire resistance of cables, the contact resistance of switches, connectors and relays, the DC low resistance of coils, motors and transformer windings, the connection resistance between metal riveted parts and metal components, and the connection resistance between ground grid and ground electrode connecting conductors. The instrument is widely used in industrial and mining enterprises, construction monitoring and supervision companies, construction units, lightning protection companies, power departments, ship locomotive factories, etc.
