» Technical Specs

In response to ever growing demands for safer and more accurate methods of testing circuit breakers, Weis has developed the Self Powered MM600 portable micro-ohm meter. It is used for measurement of resistance (μΩ) by injecting a heavy current through a breaker contact or load carrying joint.

A high current pulsed output (typically 600A DC) allows for testing of the latest arcing and main contact that rewuire 500-600A to determine the difference between them, as well as to see if they are able to carry such a current.

As a stand-alone unit, static testing can be performed with a direct readout on a built in LCD meter. When used in conjunction with the Weis SA100, SA100R or SA100RS switchgear analyser / breaker tester (having a travel input for breaker mechanism movement), a dynamic micro-ohm test can be made that will give detailed information about the state of fixed contact surfaces, moving contact surfaces, main contact, arcing contact and the complete current circuit of the breaker in every step during a close-open operation.
 
Features:
  • typically 600A DC current output, limited to 750A DC, dependant on loop impedance
  • Resistance Range: 0 to 199.9µΩ or 0 to 1999µΩ
  • Resolution: 0.1 or 1μΩ (range dependant)
  • self powered with Internal sealed rechargeable batteries
