12 best clamp meters
A clamp meter, also known as a clamp-on ammeter or current clamp, is a versatile electrical testing tool used by electricians and technicians to measure electrical current in a conductor without physically disconnecting the circuit. It is an essential tool for troubleshooting electrical systems and ensuring they are functioning safely and efficiently. Here are some key points about clamp meters:
Principle of Operation: Clamp meters work on the principle of electromagnetic induction. They have a hinged jaw-like structure that can be clamped around a conductor (such as a wire or cable). When clamped, the meter can measure the magnetic field produced by the current flowing through the conductor, allowing it to determine the current without direct contact.
Current Measurement: The primary function of a clamp meter is to measure electrical current in amperes (A). They can measure both AC (alternating current) and DC (direct current) current.
Non-Invasive: Unlike traditional ammeters, which require breaking the circuit to insert the meter in series, clamp meters are non-invasive. This means they can measure current without interrupting the electrical flow, making them safer and more convenient to use.
Multifunctional: Many modern clamp meters offer a wide range of measurement functions. In addition to current, they can often measure voltage, resistance, frequency, capacitance, temperature, and other electrical parameters. Some clamp meters are even equipped with advanced features like True RMS (Root Mean Square) measurement for accurate readings of non-sinusoidal waveforms.
Display: Clamp meters typically have a digital display that shows the measured values. This display may also include features like auto-ranging to select the appropriate measurement range automatically.
Safety: Clamp meters are designed with safety in mind.They often have features such as overload protection and non-contact voltage detection to ensure the safety of the user.
Applications: Clamp meters are used in a wide range of applications, including electrical maintenance and troubleshooting, HVAC (Heating, Ventilation, and Air Conditioning) system diagnostics, automotive electrical work, and industrial equipment testing.
Accessories: Some clamp meters come with additional accessories such as test leads, temperature probes, and carrying cases to enhance their versatility and usability.
Calibration: Like other measuring instruments, clamp meters may require periodic calibration to maintain accuracy. Calibration can be done by authorized service centers or laboratories.
Usage Tips: When using a clamp meter, it's essential to ensure proper positioning and orientation of the clamp around the conductor to get accurate readings. Additionally, understanding the meter's functions and reading the user manual is crucial for safe and effective use.
In summary, clamp meters are valuable tools for electrical professionals and technicians. They provide a convenient and safe way to measure electrical current without disrupting the circuit, making them an essential part of any electrical testing toolkit.

User questions & answers
Question: | What are the concrete tips for automatic shutdown |
Answer: | Step 1.) Run around in circles until u get too dizzy to continue or 15 min has passed, then it will auto shut off. 2.) There is no step two. If you have further questions or need more concrete tips, just continue repeating step 1 until it sinks in. |
Question: | W/ backlite on I tilt the meter away from me the display is readable but once I tilt it towards myself the display becomes unreadable, is this normal |
Answer: | Yes, with the baclklight on, it's viewable from straight-on to tilted away from yourself, but with the top tilted towards you it loses all contrast. Side-to-side viewing angle is a good. This is a common trait among some LCD displays. |
Question: | I want to measure current flowing to my car starter when cranking engine. Does this clamp on meter measure DC current when using clamp |
Answer: | Yes, It can read DC starting current with the clamp when set to DC measurement. Reading moves fast but I take video with mobile phone camera and rewind to see the 268A when starting a Nissan Frontier 2.5 L engine. Reasonable current though I cannot check its accuracy yet. I buy meter to monitor DC charging current and confirm non-running car leaking currents under 50mA but need to wait 20 minutes after engine off to let car computer stabilize from initial shutoff which can cab be as high as 0.6A. With this meter, I also find about 10mV leaking voltage on plastic surface between terminals at new battery (due to acid filling spill at manufacturing?) from club store which I need to reduce the Voltage drop to less than 0.1 mV by scribing several grooves on plastics surface around terminal posts. Calibrate to zero by holding Z/F button few seconds before measurement can help read accuracy. I am happy with this meter for the price. Hope you too if do not have time to find a better cheaper on |
Question: | how accurate is th DC current measurment |
Answer: | I have not checked it against a reference, but I have done some measurements on my car with this. It seemed to reflect a reasonable value when the battery charger was on, showing charging current. and It showed a big current for the started that was believable. When you first set it, you can press a zero button to zero it out. Then I looked at a really bad solar panel that could only put out about 50 milliamps when shorted, and it was able to show that pretty well. So the bottom line, if you are going to use this for debugging stuff, it seems pretty good. If you are going to measure calorie input to control a chemical reactions in a pharmaceutical lab, I can't say. For me, it is just cool that it can do a DC current in the first place. Has already come in handy as I was able to determine my alternator was not charging my battery quite easily. |

To measure Direct Current
Specifications:
If current> 3A, the orange display lights up.
The measuring range of DC current is 60A/600A. Accuracy: ±(2.5%+5).
Note:
Before measuring the DC current, long-press and hold the Z/F key until the ZERO character appears to clear the data.
To measure Alternating Current
Specifications:
If current> 3A, the orange display lights up.
The measuring range of AC current is 60A/600A. Accuracy: ±(2.5%+5).
Note:
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 ground wire. The current in two wires always flows in opposite directions, so the magnetic fields from two wires canceling each other, therefore the meter reads 0 A.
Grasp the individual current conductor to be measured and close the current clamp again. The measured conductor must be placed in the center of the clamp, otherwise, additional errors will occur.

User questions & answers
Question: | I need to measure volts, amps and hertz to adjust my generator. Does this model measure hertz |
Answer: | hello this model does not measure herzt. |
Question: | if I, say, clamp a 120V AC lamp cord, will it measure amps correctly? What about a 220V pool pump motor? Thanks |
Answer: | No. You have to use a AC line splitter tool found here on amazon. The line splitter plugs into the wall and then the lamp plugs into the line splitter. Then you can use your clamp meter to measure amps. this separates the neutral and the hot wire so you can meassure the amperage. |

User questions & answers
Question: | Will this read .2 amps on a tiny 22 gauge wire with 5v dc running through the clamp? can it read amps through a wrapped 2 wire (+/-) usb cable |
Answer: | This meter does NOT measure DC Current. If you had a different clamp meter that would read DC current, you would have to separate the 2 wires and place the clamp around only one to measure the current. When both +/- wires are in the clamp the fields would cancel and the reading would be zero. |
Question: | How many milli amps will the clamp meter read down to? i need one that will read 10mamps |
Answer: | In the 2/20 range it will resolve to 1 milli amp (.001). |
Question: | Is there an instructional video or other source for how to use this meter? The instructions that came with the meter are not helpful |
Answer: | Yes on youtube |
Question: | is a better detail manual available? the phamplet that came with the meter is not what I expected |
Answer: | I've worked with these kinds of meters my entire career. (Retired). I have never seen a decent instruction manual for one of any brand. But I totally agree that there is a need for more clarity. |

User questions & answers
Question: | can i get an accurate amp reading on kitchen appliances such as toasters, microwaves with this meter |
Answer: | Sounds like what you need is a Kill-A-Watt meter (brand name). You plug the meter in the wall then plug the appliance in the meter. Real simple. Gives amps, watts, volts, etc. |
Question: | Can the clamp measure voltage without load |
Answer: | The clamp (non-contact) can only measure current (amperage), not voltage. To measure voltage, you'd need to use the probes on a physical connection (terminal or bare wire). |
Question: | I am working on a light fixture - if I want to test the actual wires (and not outlet) to see if they're live, what setting would I need to do this on |
Answer: | Nobody else said it, but if you use the clamp meter, it must be around a SINGLE wire, it will not work if you clamp around both wires of the cable. You must separate the wires, and clamp only one wire. And the clamp is only gonna measure current, so if the lamp isn't working, this probably won't work. If the plag is plugged-in though, there will be a voltage present, so a non contact voltage tester should be sufficient enough to tell you it's live. Please be careful. |
Question: | people said it has an audible beep for continuity and 2 people said it doesn't. What is the true answer |
Answer: | It does have an audible beep for continuity. It is an option that must be activated by pushing a button to enable this feature of continuity testing. |

User questions & answers
Question: | Can it measures in rush |
Answer: | EVIDENTLY some "people" answer, or try to answer questions that they have no fricking idea about what they are talking about.... YES, it DOES measure "inrush", or more correctly, SURGE current. I have found that due to its sensitivity you need to select the high- 600 amp range since it will sense the current spikes that are VERY, VERY short. (IF your are measuring a smaller current, ~2-4 amps, then the 60 amp range will work). ALL you have to do is press the "min/max" button.... IF the 60 amp range does not work at first, then the 600 amp range should be selected.. THIS IS THE REAL ANSWER...... (And NO, you do not have to keep your "eye on it") Scheesh........ |
Question: | just received order and unit does not show that it is true rms. should it be posted on the item |
Answer: | Yes it should be labeled on the outside of the item where it is visible. If the description said it was true rms when placing your order, it should be.

User questions & answers
Question: | What is the DC current measurment capaility? Are there no specs for this meter other than it can read up to 600v |
Answer: | It uses a Hall Effect sensor so the AC rating is the same as the DC rating. This website has the specs that confirms that: https://www.wantitall.co.za/tools/multimeter-tacklife-cm01a-clamp-meter-4000-counts-auto-ranging-digital-tester-with-ncv-ac-dc-voltage__b01n014use I tried it on my motorcycle, and it read the starting current of ~75A fine. The paper manual said the same. I can't find an electronic copy. The Amazon UK site has more info. It shows the range as 40A/400A https://www.amazon.co.uk/dp/B01N014CTB HTH. |
Question: | Is this meter fast enough to indicate max current draw on the battery cable of a starting vehicle |
Answer: | I have used a similar meter to watch the combined starting and glow plug current on a diesel Sprinter. No problem. Since this uses a Hall Effect sensor, instead of routing the 400 amps *through* the meter, overrange current pulses should not be a problem. |
Question: | What is the resolution of the current reading |
Answer: | While this meter reads to 1 milliamp that doesn’t necessarily mean that it is accurate to 1 milliamp. It drifts quite a bit in the milliamp range. You are given the option to zero it out before taking a reading, but it does continue to drift. It is a marvel that a Hall effect meter that can read DC is offered at this price, but don’t expect +/- 1 milliamp accuracy. I am a physicist by training and at one time worked at Textronix, a premier provider of test and measurement equipment. |
Question: | Can DC current be measured by the clamp |
Answer: | It not only measures DC current accurately via the clamp but it also indicates the direction of the current. Due to the disagreeing answers on this question, I went ahead and bought it. It works really well for DC current and is going to be be an excellent tool trying to troubleshoot a vehicle battery drain. Just remember that not all clamps measure DC current. Most cheaper meters do not but this one works great for it. |

· The main function of the clamp meter is to measure current / ampere. To do this with any clamp meter, the hot and neutral wires must be separated or they will cancel each other out and give a zero amp reading.
· The battery is not rechargeable. When replacing the battery, you need to first unscrew the battery back cover with a screwdriver.
· When measuring voltage, press SEL/NCV to switch to DC or AC voltage.
· The function of measuring temperature can only measure liquid, -20~300°C(-4°~572°F)±1%+2
· The NCV function can be used when the function dial is rotated to any function key. To use the NCV function, keep pressing the SEL/NCV button.
· When the meter automatically shuts down, press SEL/NCV to wake up the meter.
· When there is no measurement, this is a normal phenomenon if the meter has a numerical value. Because there is an electric field in the environment around us, but the voltage of this electric field will be very small, the value displayed by the meter will not affect the measurement results.
· The value is unstable when measuring: it may be because the tip of the test pen does not completely touch the object being measured.
