Is there a difference between a clamp meter and a multimeter in terms of accuracy?
The ammeter must be disconnected from the circuit during measurement, and then connected in series in the circuit, which is very troublesome. The range of an ammeter is limited and cannot measure large currents. Generally, the range is 5A.
In practical work, current transformers are generally used to expand the range of the ammeter. The clamp meter is actually a combination of a through core current transformer and an ammeter, so it can not only measure AC current under constant electricity, but also easily measure large currents.
The current clamp watch is no longer the clamp watch of decades ago. It adopts the Hall induction principle and can not only measure AC circuits and DC currents; Insert the probe and transform it into a digital multimeter, which can also measure parameters such as voltage, resistance, capacitance, frequency, etc. As for accuracy, it is no different from a digital multimeter.
Their differences
If it is to be said which one is better to use than a multimeter, there are still some differences in their experience during use.
1. A clamp meter can continuously measure current, which a multimeter cannot do. If it is necessary to frequently measure AC and DC currents, it is recommended to buy a clamp meter; You don't need to measure the current frequently to buy a multimeter.
In order to continuously measure current, the clamp meter must have a clamp, so its body shape is relatively slender. Because there is no bracket on the back of the clamp watch, I personally feel that the clamp watch is more inclined to be held in hand for measurement; The multimeter has a bracket on the back, which is more inclined to be placed on a table for measurement. So if you often sit at a table for maintenance, it's better to buy a multimeter for convenience, otherwise it's uncomfortable to stretch your neck and look at the screen of the clamp watch.
In terms of price, the clamp meter not only has most of the functions of a multimeter, but also includes a current transformer, so the price is relatively more expensive.
As for which one is good to use? Radish and cabbage, each has his own love! You also need to weigh according to your own situation.
