Customer Questions & Answers

Reading from a 12 v wire

How would this read on a 12 v wires after passing through a transformer from 120v. On some possible 12 v wires I get dull light up and very soft vibration. I know it was not intended for 12 v but it still might measure in some relaible way. Thanks

Rated 1 out of 5 by from Worse Purchase Ever I should have suspected that this item was no good. Home Depot only had one in stock. I bought it and was anxious to use it but it DOES NOT WORK! I am not buying Klein products again. I was better off using a cheap tester and I really did not need to buy a new one. I will rely on Harbor Freight tools from now on.
