Clamp type ammeter; can detect capacitance;
Pure clamp meter is a measure of capacitors can.Application: usually when the current is measured by an ordinary ammeter, the circuit needs to be cut off. After the stop, the ammeter can be switched in to measure. This is very troublesome, and sometimes the normal running motor is not allowed to do so. At this time, the use of clamp meter is more convenient, the circuit to measure the current is cut off.
A capacitor, usually referred to as the capacitor that holds the charge, is represented by the letter C. Definition 1: the capacitor, as its name suggests, is a container for electricity. It is a device that holds the charge. Capacitor is one of the widely used electronic components in electronic equipment. It is widely used in circuit such as isolation, direct connection, coupling, bypass, filtering, tuning loop, energy conversion, control and so on. Definition 2: a capacitor, any of two conductors, including wires, that is insulated from each other and is very close to each other to form a capacitor.
Clamp meter is composed of a current transformer and current meter assembly. The iron core of the current transformer can be opened when the wrench is tightened; the wire through which the current is measured can be cut through the opening of the iron core without cutting off, and when the wrench is released, the iron core is closed.
Pure clamp meter (without any other function) is not the capacitance measurement.Some are measuring the resistance function of watchband clamp, which can be used for simple detection capacitance. Methods: if one lap capacitor and two pole resistance value is 0, then the capacitance can be found is breakdown, otherwise only for qualitative breakdown, not quantitative measurement of its capacity.
