If you are working in the factory as a worker, you should be very familiar with clamp meter. Of course, it is simple to know that how to use clamp meter for you. However, for the majority of people, they even have never heard theclamp meter possibly. That means they don't know that how to use clamp meter. If we would like to use clamp meter correctly, we need to understand it.
On the Industrial field, clamp meter is used far and wide. With the development of science and technology, clamp meter has been constantly improved. We need to understand that how to use clamp meter. Clamp meters are used by electricians, sometimes with the clamp incorporated into a general purpose multimeter. As the matter of fact, clamp meter is created by a current transformer, clip-on wrench and a commutator coil system consists of the reaction of instrument. It is simple to measure very high currents with the appropriate current transformer. Accurate measurement of low currents with a current transformer clamp is more difficult. It is very significant to know how to use clamp meter correctly for us.
A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of the currents. In particular if the clamp is closed around a two-conductor cable carrying power to equipment, the same current flows down one conductor and up the other; the meter correctly reads a net current of zero. We should consider that how to use clamp meter? Clamp meters are often used with what is essentially a short extension cord with the two conductors separated, so that the clamp can be placed around only one conductor of this extension.
I think the clamp meter is a good invention. Even it gives us facility on work and life but it still brings a great security risk. Therefore, we should to study that how to use clamp meter.
