  • Good tool to have.
This device works very well for checking electric and troubleshooting things. I have used it on a couple of jobs, including checking capacitors and checking for shorts. I’ve used it on the car as well and doing other electrical work sometimes very happy with it so far no problems would definitely recommend buying ... show more

  • This is a great addition to my meter group
I bought this as it serves a couple of purposes. Mainly I use it to check the inrush current on both outside HVAC units before and after soft starts being added. It also serves as a nice DMM.

Nice meter. Good price. Works as advertised.

  • Impressed
Bought this for residential HVAC diagnostics. Originally had Fieldpiece that got wet and I couldn’t justify spending $200+ so gave this one a try. Very durable, does everything I need it to do, accurate readings and easy to use. Love that it automatically turns off after 10 or so minutes, and beeps a couple times to let you know it’s about to turn off. I brag about this meter to everybody any chance I get. ... show more

  • Great meter!
I haven't had any issues with it. I just got creative with the magnet holder and it is working better than the original.

  • More than any regular homeowner will ever need
Purchase this because I recently installed a Generac generator and I wanted to be able to take readings on my air conditioning system and my generator as well as other appliances from time to time. I also do some minor electrical work around the house and often need to do continuity tests and other AC and DC testing. I will also be attending the Generac University generator technicians course to run a side hustle business maintaining generators so this is perfect for me but it is definitely more than anyone who is just a standard homeowner will ever need. If you want a high quality tool still then I highly recommend this because you should never need another tool as long as it keeps working. Really nice padded case comes with it also which is different from every low end $35 and under meter I have ever purchased. If higher end accuracy in your readings is something that's extremely important then it's worth the money. My Harbor Freight Tools higher end version of their product does not read the same as this. The HFT gauge reads about two amps higher when clamped to the same wire. ... show more
