Allen Industries service technicians and engineers offer professional Vanguard DMOM-600 micro-ohmmeter repair and calibration service. In fact, we offer repair and calibration services for many models from many manufacturers of test equipment. The Vanguard DMOM-600 is specifically designed for testing EHV circuit-breaker contact resistances, bushing contact joints, welding joints, or for any low-resistance measuring application. This high current and very lightweight (33 lbs/ 15 Kg) micro-ohmmeter is designed to meet the IEEE C57.09-1999 (5.15) requirement for testing circuit breaker contact resistance. The DMOM-600 can accurately measure resistance values from 1 micro-ohm to 450 milliohms. A 0.1 micro-ohm resolution is possible with a current greater than 5A. The DMOM-600 applies a selectable true DC test current from 10A to 600A to the resistance load to be tested. Once your Vanguard DMOM-600 micro-ohmmeter is received, our technicians will evaluate your instrument and will send you a formal estimate. Vanguard’s services are performed only AFTER approval. Standard and rush Vanguard DMOM-600 micro-ohmmeter repair and calibration services are also available.
