  1. Coy60

    Simple to operate

    Great piece of equipment we use it regularly to check our ground rod resistance easy to use great tool

    ✔ Yes, I recommend this product.

  2. Txwireman


    This is a good tool to have. It is easy to use when you follow the directions. However be aware that when you purchase this tool, if you need calibration, THIS TOOL DOES NOT COME CALIBRATED. I had to pay for it another time to get it calibrated with LOSS OF TIME AND MONEY. The customer service people were of no help to get this tool calibrated. BE AWARE!!

    ✔ Yes, I recommend this product.

  3. Amprobe

    All Amprobe products are calibrated at the time of production. So products are calibrated and adhere to their specifications at the time of sale.
    Additionally, at any time, for new and used products, we can provide a detailed NIST traceable calibration certificate, which requires retesting of the product. We record the test results and provide them on a detailed calibration certificate. Please note that this is an additional service, we charge for. Please call 1-877-AMPROBE for details.

    DGC1000A Ground ResistanceTester

    This is a very handy product ot own. It works great when you follow the direction. However IT DOES NOT COME CALIBRATED.

    ✔ Yes, I recommend this product.

    Great instrument. An advantage to have available.

    I have used the ground resistance tester for many applications. While making surge protection installatons, used to check grounding electrode resistance measurements.

    I had a inspector require me to add an addtional ground rod to a traffic signal installation service, until I proved that measurement was showing only 4 ohms at the cabinet
    Yes they do need to be calibrated, but all measurement devices need to checked for their accuracies once a year.
    Overall, this a good product / tool to have.

    ✔ Yes, I recommend this product.

    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 800hp 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 400v. 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….Just clamp it on and take live readings without breaking connections, I highly recommend it.

    ✔ Yes, I recommend this product.

  7. Jayzee

    Easy to use with no problem accurate each time I used it

    ✔ Yes, I recommend this product.
