Rated 4.1 out of 5 by 17 reviewers.
Rated 3.0 out of 5.0 by Not that great As an solar panel installer I relay on a multimeter. I have others but I needed a Amp clamp meter, so I bought this one. As a amp reader is great. But as a volt meter is inaccurate on AC and DC. Once u turn it on without the leads touching anything u start to get different readings. Even if there's no voltage on a load u still get a reading. I only use it as a clamp meter to read the amps and for voltage I use my $15 craftsman multimeter that is much more accurate than this one. Is a lot of money for a meter that is not even that accurate. March 1, 2015
Rated 5.0 out of 5.0 by All-In-One! This is the only meter you'll need. It does it all. The quality is very impressive, it doesn't feel like a toy and it isn't. It has a very handy magnet on the back, so you won't need three hands to do your testing. This has been very handy. The non-contact voltage tester is another very handy feature. Turn it on and get within range. no contact needs to be made. It does it all. The leads are of high quality and alligator clips are included. Whether you're an electrician or a weekend warrior, this is the only meter you'll need. It even has the ability to store data for later reference.With this meter, you have can measure both AC and DC current with the clamp. The display is backlit and has an analog bargraph. It comes with a handy storage case to keep everything organized and clean. This would make a great gift also. December 6, 2013
Rated 5.0 out of 5.0 by Great meter that combines old and new technologies With my old Fluke being so reliable, it's been a while since I used a new meter. Found myself needing a clamp on feature and this one is an outstanding value with so many great features. It combines the old technology that I depend on with new technology that makes my life easier. Before putting it in the field I tested against an analog meter and another digital meter, this meter proved to be right on, dead accurate. Has screw on aligator clips which are especially handy on the ground. Uses Rare Earth magnets that allow it to stick to any metal surface for hands free use. Be careful around high end electronics as the magnets could erase data, they are very strong. A bit of a learning curve as it has so many options. Loving this new meter! March 11, 2014
Rated 4.0 out of 5.0 by Good for DIY The Klein CL2000 in a good clamp meter with plenty of functions, including AC and DC current at the clamp, which by far not every clamp meter has. I like that it has a lead holder on the back, which keeps the leads from dangling around. Some measurements like capacity are a bit slow. So I would recommend this clamp meter for DIY and not for everyday use by an electrician. December 6, 2013
Rated 5.0 out of 5.0 by Replacement meter I use a meter in lot of projects for myself and others. This one has more features than my old one and is easy to use. February 17, 2015
Rated 5.0 out of 5.0 by works great and has lots of features I am a female newbie trying to diagnose issues with my minivan not starting. I bought this multimeter because of the features and the reviews and it has not let me down yet, although I have not used all the features yet by far. Using the multimeter, youtube, and a little advice from a mechanic, I determined that I have a parasitic drain on my battery- as opposed to a problem with the alternator. this tool is very handy, the magnet that allows me to 'attach' it to the car so that I have both hands free, the solid construction all live up to the reviews I read prior to buying it. The clamp meter that allows you to test not only ac but also dc voltage is a plus that it appeared was usually on much more expensive multimeters. When I have time, I have a few other things that need to be repaired so this tool will come in handy. December 10, 2014
Rated 5.0 out of 5.0 by Excellent hand-tool for the serious electrician Klein CL2000 is an excellent hand-tool for the serious electrician. I've used and owned dozens of meters over the decades. Each has its own personality: great for some things, less-so for others. This led to specialized meters for each profession. Klein is well-known for its professional electrician tools: great wire-pliers, screwdrivers, hole-punches, wall-drills... a full line. The Klein CL2000 is very handy. Fits nice in the tool pouch. Fits great in the hand. Dial and buttons can be worked with one hand. The magnet on the back works great! It is strong enough to hold securely, with felt cover so it doesn't clang or scratch and comes off nicely. Probe can be snapped to the side for one-handed probing in fuse-box or outlet. You can turn-on lighting for the display and the work area, very useful. Beats the heck out of general-purpose multimeters that need three hands and a shelf. It is clear that Klein worked with practicing electricians to develop the CL2000. You find similar handiness in Klein's CL1000, which sells for about 2/3rd the price of the CL2000. Many users will be well-served by the CL1000. It omits some rarely-used frills (notably "true RMS") but does all the usual tests and is equally handy. Digital meter technology is mature. Even low-price meters have ample accuracy and range. Of course low-price meters fall-down on reliability, robustness, and extra features. The CL2000 boasts "true RMS" AC metering. Any meter can read a nice round Sine wave. RMS is "right", however an Averaging meter will be calibrated for RMS of a Sine. Non-sine waves can be read several ways. Most electrical work is with pretty-good Sine waves, so RMS is not essential. I have seen specialized uses, such as calibrating theater lamp-dimmers, which must use true-RMS metering. I have done limited drop-testing on the CL2000 with no effect. It is light yet the case seems extremely strong, with rounded corners so impacts and strains are not concentrated. I also have a lab-quality meter and did some cross-checking. The Klein CL2000 appears to meet its published accuracy specs with ample margin. It is important to note that, in any digital meter, the right-most digit is never exact. In this meter, that last digit may be noticeably in error, especially for very low voltages and currents (under 10mV and 10 Ohms). This is rarely a problem, just something to keep in mind. Meter-loading is important in high impedance circuits (rarely found in electrical work). The input impedance, ACV or DCV, is about 8.5 Megs. This is similar to the 10 Meg of classic bench meters. While the specs imply a wide range of current measurements, there is a gap. You read zero to 2mA (0.002A) through the leads (after breaking your circuit). You read 400 Amps with the clamp-on feature. Readings between 0.002A and about 0.1A are not possible, either way. Note that most electrical work will only use the clamp-on range, which does cover all currents normally found in electrical circuits. I hate dead batteries. This meter needs two AA cells. I measured the CL2000's drain. A couple heathy cells should run it for a couple hundred hours non-stop. Very thrifty! You don't need to turn it off between readings. One night left-on won't drain it. Current consumptions doubles when the back-light feature is used. December 6, 2013
Rated 4.0 out of 5.0 by Works Great Great features for the price. The work light is an LED at the back of the clamp ring and a simultaneous display light at the reading. The ncv works great and so does being able to slide a lead into the side of the clamp claw while jumping from circuit to circuit with the other lead. Check capacitance and ac/dc voltage with the rotation of the knob. And a strong, felt skinned magnet on the back to gently hold wherever you put it. Readings may take a sec to average but if you can't wait that long, buy a Fluke. March 30, 2013
