Amprobe DGC-1000A User Manual

Rated 5 out of 5 Petroelectrician — April 23, Chase the inspector!!!!! We have used this tool for simple functions like only installing one ground rod and verifying reading to ground on a service upgrade or new install, to inspecting motor grounding. On a motor grounding job where hp motors were failing on a continuous basis, we were able to pinpoint the lack of proper grounding that was causing harmonics and energizing armature shaft, to the point where it was reading v. On that job alone this tool proved invaluable and allowed the customer to save thousands on downtime and predictive maintenance. If you are an industrial electrician or even a commercial or residential guy there are many applications that this tool will become a gem in your tool-bag that in previous times would be impossible to read without shunts and extra setup….
