Amprobe - 2740452 ACDC-100 1000A AC/DC Clamp Meter

Done good first time out. Once scraping the ends of some really corroded jumper cables showed a 15 amp pull from my little Honda's alternator to a big Ramcharger truck battery that went dead. Got it settled down a little to 12.5 amp and started the truck. Probed the truck alternator and found it delivering 70 amp to it's battery. Highest I ever saw was an 80 amp draw on a 12 volt alternator that was hooked up to do welding underground in a coal mine with a probe that cost three times the price. Invaluable tool.

Purchased for use on the job and has worked flawlessly every time. Amprob makes great quality meters along with fluke, only two brands I trust when it comes to meter testing.

I bought this for home and personal automotive repair use. I spent more for a unit that is capable of 1000 Amps DC so I could hopefully be able to diagnose automotive starting issues should they arise. Amprobe is actually owned by Danaher Corp which also owns Fluke so Amprobe is kind of the Chevy to the Cadillac Fluke. This meter works well for personal purposes, but as an actual electrician I would recommend something better for professional use if your job requires frequent use of a meter. If you only use a meter every two months to verify voltage or find a short this meter is actually probably more than you need.When you initially turn the meter on to detect amperage the default setting is DC. You have to press the "select" button to switch to AC. You'd think AC would be the default setting. The selector gauge requires the use of both hands to operate and the leads are a bit flimsy. The readings take quite some time to come up and I've noticed that after taking an amperage reading the meter will drop down to about .5 amps and stay there with no wire in the jaws. When you operate the ammeter jaws you can hear the spring stretching and unstretching - not a huge deal, but noticeable. The unit feels sturdy enough and the reddish part of the housing is rubberized. The "select" button doubles as your way to activate the lighted display for those times when you're in the dark.I would've really liked to see Hz/frequency offered as I have seen much less expensive meters offer it, but I suppose Amprobe didn't want to take business away from their higher end meters. I would've traded the capacitance feature for Hz/frequency. In eight years as an electrician I've never needed to know capacitance. By the way, the slow response does not seem to affect the ability of the meter to successfully display inrush current when using the MAX HOLD feature. The manual says that response time when using the MAX HOLD feature is 30ms. They don't mention a response time for any of the other features, but I can tell you it's more like 2-5 seconds. It's like the meter can go fast when it needs to for the MAX HOLD feature but they detuned it for everything else. Again, maybe so they don't take a lot of business from their higher end models.It definitely is a good meter with a lot of capabilities - for the price. If you want faster response and more intuitive design be ready to shell out at least double the money for the same features.

One of the reasons I purchased this Amprobe meter was to measure Inrush current. The meters inrush function is supposed to give you the initial high amperage draw of devices being tested. I tried measuring inrush on 2 220V motor circuits and 1 resistive load heating unit. This meter failed to register inrush, it only displayed normal running amperage. I set the meter to the "Max Capture" function which is supposed to measure the first 30 milliseconds of current flow, so I don't think it was operator error.I tested all other functions and they seem to work well.Meter response is a bit slow overall. The meter is well built and a good buy if you don't need the Inrush current function.I got a refund through amazon which went very smooth. I compared the Amprobe units Inrush to a Fluke 336 which has a proprietary Inrush function, the Fluke worked fine with the same circuits tested.

A nice instrument at a good price, thanks ed

Oh baby! If there was a sexy ac/dc multimeter, this would be it. Wonderful. I love it. The only thing I could wish for is that the metal tips of the leads were longer. I need to use the leads from my el cheapo multimeter if it's a tight measure.

I got this for amp readings on automotive and I asked community and the people selling it and was told it will read amps on automotive side, NOT, so now I have another regular meter

I got a new one of these with damaged packaging for a very low price. I wanted something for intermittent use at a remote cabin to check battery bank loads, solar charging, etc. While I have a very accurate shunt on the system, with the clamp I can check any of the dozens of wires going from individual solar panels, batteries, loads, etc. to get more information.
