Does exactly what I bought it for. A bit on the pricy side for what it is though. The only reason I bought it was because it fits perfectly in my small tool bag with my 87V.

Style: AC CURRENT CLAMP-ON PROBEPattern Name: ClampVerified Purchase
I use this AC current transducer with my Fluke Model 189 DVM to measure AC currents in single and polyphase systems. It does the job safely, accurately and with a minimum of fuss and effort on my part.

Note that this device will measure AC currents ONLY - it you need to measure DC currents or AC currents with a DC component this is not the appropriate device.

The leads are equipped with safety plugs - these keep dirt and foreign material out of the recessed contact areas. These plugs must be removed before connecting the leads to corresponding recessed sockets on a meter. Note that the connectors must be connected to corresponding AC current input inputs on meters - they WILL NOT work on DC current or any type of voltage inputs.

The clamp-on part of the device is nicely designed - it's easy to slip into a tight breaker panel or around the leads feeding a main panel. It requires only one hand to connect in keeping with best safety practices (one hand in the panel, one hand behind your back).

You can't go wrong with this unit.

Style: AC CURRENT CLAMP-ON PROBEPattern Name: ClampVerified Purchase
Great probe once you learn how to use it.

Note: On my Fluke 175 (and many others), it reads in mA, not A. That's pretty clearly stated in the directions, so no big deal.

Note: You cannot put an amp-clamp on a power cord and get a reading. Why? Because the AC signal essentially goes in the hot wire and out the neutral and those two signals cancel each other out. You need to put an amp clamp around the hot wire only (or the neutral assuming a properly wired connection, but really it should be the hot.) Unless you have the wall or panel open, this is not possible so you'll need an "AC line splitter". Amazon sells a bunch. I have the Amprobe ELS2A and like it fine.

This probe is very well made, has a nice solid lockup, and the cable is flexible enough that it doesn't get in my way.

Why not just get an all-in-one ammeter? For me, I like to hang just the clamp in the wires, then have the meter on the floor (or whatever) that I can look at. I also don't like manipulating dials and what-not right in a service panel. Those all-in-one units make me want to take my hand out of my pocket. :) Plus, I can use this on my handheld Fluke as well as my bench-top meter.

Style: 400A AC/DC CURRENT CLAMPPattern Name: ClampVerified Purchase
I purchased this clamp-on probe to use with a Radio Shack Model 22-812 multi-function digital multimeter and the combo is superb. The plug, a ganged two-prong (positive and negative) shrouded banana plug duo, has a spacing of exactly 3/4 inch, which Fluke and many other manufacturers use, like my RS MM. Thus, I can use it on the RS, Flukes, and others. One caveat is that the output is 1 mV per Ampere; hence, one must use a MM having a sensitivity of at least 1 mV, which is no problem for the RS 22-812 and the better lines of most MMs. So, even tho the plug may fit your, for example, Wavetek Meterman Model AC40A, a compact and simple combo AC current/Voltage/resistance-measuring digital MM (yes, I have one; it's great for normal Residential, Commercial, and Industrial work when you're measuring Voltages LT 600 V)(AC and DC Voltages read, but NOT DC current, which is why I purchased this probe), its sensitivity is only 100 mV (0.1 Volt), making it worthless for most current readings.

I specifically purchased this probe over some others, which are cheaper, because it's made by Fluke. Simple as that. I have yet to encounter a shoddy Fluke-made product, and when you need to have a current reading, be it AC or DC, a precise number generated by a product that will perform reliably in a work environment, especially when you have to physically clamp onto a conductor that may or may NOT have intact insulation, for years to come is well worth the extra dollars.

So...you might ask why I use a RS meter costing only $80 versus the equivalent Fluke (a Model 87) costing [...] (at [...]). Well, the answer is two-fold: availability and price. I live and work in Ecuador and quality electrical test equipment is not all that available. The RS meter was at a company store here and it was on sale for the "List Price:" [...]. There's normally a significant markup and many items are not available. As for the second factor, a Fluke 87 is NOT 4.75 times "better" than this specific RS MM!

In conclusion, if you need a Hall Effect current probe (so you can measure DC as well as AC), this one will serve you well.

This is a hunk of an instrument. I trust Fluke to provide a calibrated tool but I didn't need something so large. I'm keeping it though because someday, I'll hook it to the Grand Coulee Dam to measure their output current. Seriously, it's a Fluke. It is trivial to use and sensitive enough for small stuff.

Style: 400A AC/DC CURRENT CLAMPPattern Name: ClampVerified Purchase
Adding a couple of thoughts and facts to the other reviews I see here, the following:

(1) Capacity of the i410 clamp is 400A--number given on Amazon's page is 1000A. The i1010 will do 1000A if you need that much sauce.

(2) Bandwidth limit on this clamp is 3kHz. This turned out to be an issue for me, but I don't blame Fluke. I have yet to see a shoddy product wearing the Fluke brand mark. I always, always, always buy Fluke electrical measurement kit.

(3) Tactically, a good reason to get a clamp for your DMM instead of a dedicated clamp meter is that using a clamp you can put the display where you want it. If you get a dedicated clamp meter (i.e. single-piece clamp with current display) then the display is constrained to be wherever you're measuring the current. Not always convenient...and this is why I bought the i410. I happen to have VOMs all over the house but needed one with a higher current capacity.

(4) As expected this product is solidly built and easy to use.

(5) Y'all keep one hand in your pocket, now, mmmkay?
