Clamp Ammeter
The clamp-type ammeter is mainly used to measure the current of the wire. It has a transformer on the meter head. When the wire passes through the transformer, if there is a current passing through the telecommunication, it will act on the transformer, and the corresponding current value will be fed back. In a clamp ammeter, this is the principle of a clamp ammeter.
Of course, the multi-function clamp ammeter also carries test leads and other voltage resistance gears, and can also be used as a multimeter, and the clamp ammeter is also divided into pointer type. There are transformers, so it is more troublesome to carry.
multimeter
The multimeter is one of the most commonly used electrical tools as an electrician and electrical engineer. The multimeter is divided into pointer type and digital automatic type. Because the pointer is more troublesome to zero, we now use the digital type.
There are many multimeter gears, including voltage gear, resistance gear, current gear diode gear, and buzzer gear. For example, we commonly use the voltage gear, electric block and buzzer gear. We only use other gears on special occasions. , like the current file, because it is relatively dangerous to change the position of the test leads and connect them in series in the circuit when measuring the current.
Therefore, when we measure current, we still use a clamp-on ammeter for measurement, which is convenient and fast, but when measuring other data, we still use a multimeter.
