What does a clamp ammeter do to measure voltage?
Clamp meter is a kind of instrument used to measure the current of running electric circuit, which can measure the current without interruption. The clamp meter is actually a current transformer. The stuck wire is equivalent to the primary coil of the transformer. When there is current in the wire, magnetic flux will be generated in the iron core of the meter, and then current will be induced in the secondary coil of the meter. This current is equal to the current in the primary coil multiplied by the turns of the primary coil (it is a wire, so it is a turn) divided by the turns of the secondary coil, and then according to this relationship, the current in the wire can be converted.
The clamp ammeter is actually an electromagnetic inductor. Each electrified wire generates a magnetic field, and the intensity of the magnetic field generated by the current is different. The current value converted on the clamp ammeter is different because of the difference of three-phase voltage, so the current hole on each phase is different, so only the single-phase current can be measured, and then the average current can be calculated. Finally, whether it is three-phase 380v voltage or two-phase 220v voltage, the method used is the same.
The clamp ring of the clamp multimeter is set for measuring current, but since the clamp multimeter is called, it is not only a function of measuring AC current.
Many clamp meters have the functions of measuring resistance, AC/DC voltage, etc. Simply put, the functions on ordinary multimeter can be done on clamp multimeter. Many clamp meters have the function of measuring DC current, but at present, most of them use pens instead of clamp rings.
Switch to the current gear, and just clamp the wire to be measured with the caliper.
Some clamp meters can measure voltage, while others can't. Anyone who can measure voltage is equipped with a stylus. Insert the stylus into the corresponding hole, adjust it to the voltage range, and put two stylus on the voltage point to be measured, such as a live wire and a zero wire.
