What is the difference between clamp meter and multimeter accuracy?
The ammeter must disconnect the circuit when measuring, and then connect the ammeter in series in the circuit, which is very troublesome. There is also a limited range of the ammeter, which cannot measure large currents, and the general range is 5A. In actual work, current transformers are generally used to expand the range of the ammeter. The clamp meter is actually composed of a through-core current transformer and an ammeter, so it can not only measure the AC current under continuous power supply, but also can easily measure large currents.
The clamp meters of today are not the clamp meters of decades ago. They utilize the principle of Hall sensing and can not only measure AC circuits and DC current, but also measure voltage, resistance, capacitance, frequency and other parameters by inserting a probe into the digital multimeter. As for accuracy, it's the same as a digital multimeter. difference between them. If you have to say which is better, pliers or a multimeter, their experience in use is still somewhat different.
1. Clamp meters can measure current continuously, while multimeters cannot. If you need to measure AC and DC current frequently, it is recommended to choose a clamp meter; if you do not need to measure current frequently, choose a multimeter.
2. In order to continuously measure the current, the clamp meter must have jaws, so its shape is relatively slender. Since there is no stand on the back of the clamp meter, I feel that the clamp meter is more likely to be held in the hand for measurement; the multimeter has a stand on the back, which is easier to place on the measuring table for measurement. So if you often sit next to the watch for maintenance, or it is convenient to buy a multimeter, otherwise it will be very uncomfortable to stretch your neck to see the clip screen.
3. In terms of price, the clamp meter not only has most of the functions of a multimeter, but also has more current transformers, so the price is relatively more expensive.

You still need to weigh it according to your own situation.
