The Fluke true rms clamp meter is a great clamp meter for general, grab and go troubleshooting needs. The FLUKE 325 is ideally suited for current measurements up to 400 a in tight cable compartments.
Digital clamp meter measures AC current to 400 amp, AC and DC voltage to 600V, and resistance to 4 kilohms
True RMS sensing meter provides accurate readings when measuring linear or non-linear loads, regardless of waveform
Jaw opening measures current in a conductor up to 30mm without touching or interrupting the circuit
Audible continuity sensor confirms that the circuit conducts electricity
Meets IEC safety standard 61010-1, and is rated for CAT IV installations to 300V and CAT III installations to 600V
400 A AC and DC current measurement
Resistance measurement up to 40
Ac voltage make for the most accurate measurements on non-linear signals
Temperature and capacitance measurement
Frequency measurement
I have a non-clamp version of this multimeter and had to get this so I can take amp draws on motors. This is no doubt a serious upgrade. Only thing it doesn’t do is check diodes, but that’s what the other multimeter is for (small Arduino circuits and stuff). This covers the entire range of what I need it for at work. Yes it’s a little spendy, but this is a gosh darn Fluke we’re talking about. It absolutely slaps when working with big power. Would gladly always choose this over the competition any day of the week. Reliable, built to last, and the dial is perfect for one-handed operation. Comes with a thermistor and carrying case. If you’re even thinking about shopping around, do yourself a favor and treat yourself to this perfect-in-every-way multimeter.The lead are made of the same old Chinese thermoplastic and not rubber. They feel like they will eventually crack, unlike the Beckman meter I have had for 30 years.The combination of functions is unbeatable.What a quality piece of equipment! I have owned several multimeters over the years, but none of them were as well made as this Fluke. It is also easy to use and very simple to learn. I am entirely pleased with it and look forward to many years of service from it.I received an unhelpful vote on the above review so I will attempt to give more information to rectify it.I purchased the AC/DC version of this meter with temperature measurement. My first impression of this product was one of quality.The yellow and black soft case is well made and provides plenty of room to keep the probes in it along with the meter. I do my best to protect my tools and expect this case to last me well, as I won't be abusing it. Now if someone was to throw it in their toolbox and drop other tools on it repeatedly, I expect that it would not last long. But for the normal person, it should hold up well.The test leads have good quality probes attached to a fairly heavy duty wire terminating in well made banana plugs. The plugs fit securely in the meter, but aren't too hard to get into the meter. I didn't measure the full length of the leads but they are of sufficient length and seemed to be just a tad longer than most leads. As the probes have very sharp points, there are caps for them provided.The included manual is very thorough and an electronic version is available for download at their website to carry on your phone or tablet if needed in the field.I tested the meter with 115volt AC, 230 volt AC, 0 to 30 volt DC, multiple resistances including a potentiometer, AC current from 1 to 30 amps, DC current from 2 to 180 amps, and multiple temperatures. I tested against other meters and thermometers I had and I was quite satisfied with the Flukes accuracy. I like the fact that I can use this one meter instead of having to grab two or three other meters because of different kind of measurements on the same project.The data hold feature really comes in handy when you are in checking amperage and the lines that you are checking are too big to be rotated to where you can see the meter face.This was a splurge purchase for me as I don't work use this meter in making my living. I am an advanced do it yourselfer who likes to have good quality, long lasting tools and I was glad to see my money was well spent. I am completely satisfied with my Fluke 325.We use Amazon for most of our purchases and I update my reviews if anything changes with the products. I do this so other Amazon users can get a real feel for the life of the product. I am not associated with any company and all opinions are my very own.I got this meter to help with parastic draw tests and because it was a Fluke.The meter is pretty great, it's light, but also feels like you could smack someone around with it and it would be completely unscathed. The backlight is decent, but not great. If you're in a dark area it'll be better than nothing.The case is JUST big enough for the meter and the leads to fit (folded up), it doesn't fit the meter with the leads attached. I do like how small the case is though. I can attach it to my pants with a carabiner and it's not too bad.One thing that bugs me is that Ohms measuring and continuity testing are combined into one and there's no way to choose between the two. So if you're trying to test the resistance of a switch or fuse the meter will be beeping the whole time. I have had a couple instances with testing the Ohms of a wheel speed sensor where the meter determined I was doing a ohms measurement and shut off the continuity test. I'm not sure how or why it did, it's very ambiguous, but it seems the meter has some way of determining what you're trying to do.The clamp is slightly slow, it'll adjust until it gets the right measurement, but rest assured you can be confident that it's displaying the measurement with confidence.It's a fantastic meter and definitely the best near $300 I've spent, the only reason I don't use it a lot is I don't like leaving my meter in the bay I work at when I'm not there and sometimes forget it in my other car that contains all of my other tools.Update:Just wanted to share a bit of an update. This meter doesn't read millivolts very well. You'll only be able to read to the 100's, so you couldn't see something like 0.01V on the meter. So doing a test like AC ripple with this meter will prove fruitless unless you're getting an egregious amount of AC through your battery.Still love the meter, but make sure you have another meter that can go down to the mV scale if you're gonna be doing tests like this.I have relied on Fluke meters for over 25 years and they never disappoint. This purchase made the 2nd one of these in the past 10 years of constant use. (my other one fell and broke) This is the perfect size to keep on my tool pouch and always at the ready with the most important features that an HVAC Tech would ever need. Price point is good for the features, ruggedness, and utility. No complaints with the meter or the seller. It came quickly and was used immediately after arrival with no problems.Expensive, but everyone says it's worth it.As you probably expect, this is a top quality and reliable meter from Fluke, which feels solidly built and isn't lightweight for its size. The clamp spring is firm, but not awkward to open and the dial increments smoothly between settings.The Type K thermocouple is fitted with a fixed double plug, so it fits snuggly into the test sockets on the bottom of the meter and the solid core cable is approximately 90 cms long. The meter will read in Centigrade of Fahrenheit.The probes are approx. 140 cms from tip to plug and are built to the usual high Fluke standards. They have a removable safety guard on the probes.It has a latched continuity beep, so no scratchy sounds when you are testing in awkward positions.So, it's built to last (I still use a Fluke from 1985) and won't let you down.Get a decent set of test leads . The leads supplied are like probes on the end of springs ? Paid a premium for a fluke meter which is excellent. Shame about the test leads.A great bit of kit that I use on Electric Motors and Electrical Distribution Boards. My only disappointment was having received it on time I had to get it calibrated before being able to take onto some sites costing me more than I would have wished. All in all a good piece of kit.Used for measuring dc current on a hydrogen generator to get electrolyte concentration correct.Very good
