About this item

  • Important Tips - This CM2K0R clamp meter can not test DC Current. To measure the AC Current you need to clamp the meter around one of the wires and not the whole power cord. Ensure the conductor to betested is in the center of the clamp head. The clamp Jaw is only used to measure current. Do not measure voltage by clamping the conductor being measured.
  • Versatile Digital Clamp Meter - Accurately measures AC/DC Voltage, AC Current, Capacitance, Resistance, Diode Continuity and Live Wire Tests. This clamp meter is a really useful tool for solving industrial and household electrical issues.
  • Thoughtful Design - Support Data Hold, Max/Min, Auto Shut-off, low battery indicator and continuity buzzer. Includes Convenient features like Audial and Visual Alarm, LCD Backlit Screen and Flashlight make it easy to use. Two 1.5V AAA batteries are included in the package.
  • Non-contact Voltage Testing - This Clamp Meter features non-contact voltage testing with sound and light alarm. When the Meter senses a weak AC signal, the green indicator light will come on and the buzzer will emit a slow, audible beep. when the Meter senses a strong AC signal, the red indicator light will come on and the buzzer will emit a quick beep.
  • Enhanced Safety - The clamp meter has passed the environmental pollution degree 2 and overvoltage category III 600V safety standards. If you have any questions about the product, feel free to contact us! Our California-based support team will respond within 24 hours.



Product Description

1

Important instruction: This CM2K0R clamp meter can not test DC Current.

Note: The clamp Jaw is only used to measure current. Do not measure voltage by clamping the conductor being measured. To measure the current, you need to clamp the meter around one of the wires and not the whole power cord. The power cord contains two wires carrying current and a ground wire. The current in the two wires always flows in opposite directions, so the magnetic fields from the two wires cancel each other; therefore, the meter reads 0 A.

The NCV function can test the voltage without contact. When the Meter senses a weak AC signal, the green indicator light will be on and the buzzer will emit a slow, audible beep. When the Meter senses a strong AC signal, the red indicator light will be on and the buzzer will emit a quick beep.

PLEASE ATTENTION

Incorrect operations may cause no work or inaccurate readings:

  • Incorrect current: The conductor to be tested is not in the center of the clamp head. (Refer to the right picture for correct use.)
  • Incorrect voltage: The plugs of test leads are not fully inserted or not inserted into the correct sockets. It will cause incorrect voltage readings or the clamp meter may not work.
  • Doesn't work: Clamp the whole power cord when measuring the current. You need to clamp the meter around one of the wires.

I really like this device because the ease of use and its ability to detect electricity through the clamp but still has the probes. I am not an electrician and lack knowledge in that area but this device is simple and has good instructions. It works great for what I use it for. The screen is bright and is easy to see and read. The cables have quick connects and decent length of cords. I would recommend this for the experienced as well as the novices.

This digital clamp meter feels like a more expensive piece. The rotary dial is turned with your index finger with one hand insted of having to hold the meter in one hand while pinching the dial with thumb and index to select a function.The option to illuminate the digital readout screen is nice. The readout is easy to read.You can save your readout by pushing the hold button.The flashlight is bright and located well.The test leads are substantial, should last for a long time.Customer service was readily available and helpful with my questionThe batteries are preinserted so the tester is ready to go.The user manual is pretty good. If you haven't used the transformer jaws before find a video.

From reading other reviews, it seems a lot of people aren’t capable of appreciating this meter for what it is; great up to date technology at a bargain price. It’s not a Fluke, it’s not supposed to be. I would be willing to bet that some of the circuitry inside this unit is newer and more capable than what you might find in your dated, “professional” model.This meter has all the features needed for the average DIY and hobbyist. And it does take some amount of learning to use this or any meter for the wide variety of tests it is capable of. From reading other reviews, it is apparent that the meter is being unfairly criticized for user error; in particular, there are a lot of folks that need to understand how a clamp meter works to measure A.C.Dislikes: I don’t really care for the overall size- I think it would be easier to operate if it was a tad larger. And I don’t like or trust the NCV detector feature- I have not found one of these I could trust yet, on any meter at any price. The display could also be a little brighter.Overall, this is a solid choice for anyone needing to add testing capabilities to their hobby or household.

Feels solid in your hand, the built-in flashlight is a plus, is accurate enough for my daily uses. the digital readout is clear, and an audible peep alerts you when changing modes etc.- the ability to measure capacitance was a real plus- I have several other meters and an oscilloscope, but had no way to measure capacitance. Used the capacitance function to troubleshoot a ceiling fan - the Hunter fans depend on various values of capacitors to regulate speed and I hate buying and trying- got it going in this case the capacitors weren't bad, had an open connection, the meter made it easy to exclude the capacitors as being faulty. - The amp probe came in very handy in the first week- I have another amp probe meter and setting up two meters simultaneously on the incoming buss lines made it much easier to balance my generator circuits coming into the house during a recent power failure- you can always get sneaky parasitic loads from things like the refrigerator going into defrost mode, or an automatic pump coming on on a timer or switch, and if you are close on one breaker, it can trip you out, even if your total load is still OK. So for this price point, and other nice features- I give it five stars- Downside- be prepared to buy a nice lead set if you really want to get the most out of it- it has a very minimalist lead set with it.

This a really nice AC clamp meter + auto-ranging multimeter that's really easy to use, well-built, sold at a very reasonable price. The AC clamp meter is for measuing AC current on single wires. The multimeter functions are pretty standard: VA, VC, Ohm, continuity, etc... with the bonus that it's auto-ranging, and there are only 2 probe ports (other multimeters have 3), so all you have to do is plug in the red probe, the black probe, and the multimeter auto-senses the range and displays the right value. There is no need to guess what port to plug in the probes. The size is compact and slim. 2 wire probes are included. The 2 required AAA alkaline batteries are included in the box, which is a nice touch. There is a protective cordura nylon carrying case with a handle too. You could buy a regular multimeter for about the same price, but this one has a non-contact clamp meter current sensor + non-contact live wire detector + auto-ranging multimeter, and it's easier to use, so it's a no-brainer.

This is an outstanding meter at a really reasonable price. It replaces a 40 year old meter that got a soaking in Hurricane Helene. It is accurate, easy to use, and has plenty of functions. It is compact in size and very light. The clamp is extremely helpful. It requires 2 AAA batteries for operation which are included. 2 probes and a nylon carrying case are also included. The meter is a very good value.Damon M. Tatem
