GTC CM1000 1000 Amps AC/DC Current Clamp Meter by General Technologies Corp

Very happy with this purchase. It looks and feels like a very quality product. Easy to use and read. I have tested it against other meters for accuracy and it tests right on. A must if dealing with high amperage accessories on your vehicle as well as working with a solar array on your house. Highly recommended.

Spend more money and get good Quality unit …garbage waste of money

I have only used it once so far. It is very easy to use (clamp and read) and it seems to be accurate ( I duplicated verified readings). I consider this a very purchase.

Work great

Just what I needed.

great price

Easy to use, great product

This meter paid for itself in a single diagnostic test. I found which string of solar panels was open circuit by testing the 3 positive and 3 negative leads in a junction box closest to the inverter. Then I twisted the wire nut on the one with 0 amps and heard crackling. A retest revealed that current was restored to 7.8 amps. Since there's no way to turn off the solar array I'll wait until dark and wear rubber gloves to replace the bad wire nut. This kind of diagnostic test is almost impossible unless you have ability to measure DC current in a non-invasive way. BTW, voltage at the inverter was still normal so I could not tell which wire was the problem until I switched to DC amps. The GTC CM-1000 has been a novelty for me up until now, just checking things like car battery chargers, alternator, etc. But now I have found the application for which nothing else will do!

Great price and great product

Exactly as described. Amazingly fast shipping.
