A clamp meter is a device for taking electrical measurements such as voltage, current, and resistance. It is meant for use in laboratories, in field electrical works, and within homes. It gets its name from the fact that it comes with ‘jaws’, which one needs to clamp onto circuits. Thus one clamps circuits with the meter’s jaws, to get readings. The readings that one gets from a clamp meter may be in volts, amperes, ohms, and so on. It all depends on what is under measurement.

Top 10 Best Clamp Meters in India
Features of Clamp Meter
- Accuracy is arguably the most important feature of a clamp meter. The last thing one needs is a meter that gives inaccurate readings.
- Another key feature is display quality. The best clamp meters come with clear, easy-to-read displays. And they provide readings up to reasonably small units.
- Yet another key feature in clamp meters is jaw size. This determines which types of cables or circuits you can take readings from using the meter.
- On another note, the best clamp meters come with data holding features, as well as range selection features.
Types of Clamp Meters
- There are clamp meters that are mostly meant for use in laboratory settings. Then we have others that are most suitable for use in homes and in routine electrical and electronic repair works.
- There are 6000 counts of clamp meters. Then there are 2000 counts clamp meters, among others.
- We have clamp meters that measure just a few things (like the voltage, current, and resistance). Then we have others that measure a wider range of things, including frequency/duty cycles, capacitance, diode, and continuity tests.
- There are clamp meters with backlit LCD displays. Then we have clamp meters that have non-LCD displays.
Buying Guide for Clamp Meter
- You always need to start by asking yourself what you are buying the clamp meter for. Is it for laboratory work? Or is it for routine electrical and electronics repair work? Could it be for DIY projects? Or is it for professional work? This will help you in picking the best meter for your needs.
- Ensure that the batteries that power the clamp meter you are buying are easily available. Also, check how long it keeps batteries before they get depleted. And check whether it has features to turn itself off when not in use for given periods of time.
- Only buy a meter that gives readings with decent accuracy. Check how well the meter displays its readings, and how easily readable they are.
- How heavy the meter is (its weight) will help in working out how easy it will be to carry around.
- Pay some heed to the clamp meter price. Don’t assume that a higher clamp meter price always translates into better quality. But also don’t be afraid to pay a higher clamp meter price, if there are good qualities to justify it.
How To Use Clamp Meter?
- Upon receiving the clamp meter, you usually first need to place batteries in it, for it to work. In some cases, the clamp meters are shipped together with batteries. But in other cases, people have to buy the batteries separately.
- Once the meter has batteries in it, check its accuracy. This you can do by using it to measure a circuit whose readings you already know. That is to see how well the meter’s readings align with those.
- To actually take a reading using the clamp meter, first open its jaws. Now place those round the cable or circuit whose reading you wish to take. Close the clamp. Adjust the knob, as necessary. Check the meter’s display. It should now be showing the readings you were seeking.
- If the meter is one of the more sophisticated, it may give voltage readings without touching wires: through NCV detection.
