Clamp meter is initially used to detect AC current measurement is running line current size instrument. As you can see, current detection was possible without breaking the power supply and was specialised in detecting high AC currents. Today's clamp-on meters are no longer mono-functional; they have all the functions that a multimeter has, but they also have the same functions.

1. Clamp meter it can be constantly measuring current, which the multimeter can not do. If you need to frequently measure AC and DC current, it is recommended to buy clamp meter; do not need to frequently measure the current on the purchase of the multimeter.

2. In order to measure the current without power, the clamp meter must have jaws, so its body shape is relatively long. Because there is no bracket on the back of the clamp meter, I feel that the clamp meter is more inclined to hold in the hands of measurement; multimeter has a bracket on the back of the more inclined to be placed on the table to measure. So if you are often sitting at the table next to the maintenance, or buy a multimeter is convenient, or stretch your neck to see the clamp table screen is very uncomfortable.

3. From the price point of view, the clamp meter it not only has a multimeter of large multi-function, but also more current transformer, so the price is relatively more expensive.
