Clamp ammeters how to measure resistance, current, voltage
A multimeter and ordinary multimeter is not the same as lies in: as the current measurement to the meter in series in the circuit, so under normal circumstances, using ordinary multimeter to measure the current required power cut, multimeter or current meter, current transformer primary side connected in series in the circuit. Then power is measured, and a multimeter can measure the current power. A multimeter than the ordinary multimeter more than one meter, the meter is made according to the principle of the current transformer, specially used for measuring alternating current. Its working principle is as follows: a part of current meter measurement million by the current transformer and current measuring part composed of 000 table. The iron core of the mutual inductor is provided with a movable part and is connected with the handle. When the utility model is used, the movable iron core is opened by pressing the handle. The wires of the current to be measured are put into the jaw and the handle is closed to close the iron core.
Usage:Although the clamp meter is similar, but each kind of table usage due to the design of the use of different methods are also different, so the user must read the instructions carefully before use.To be on the safe side, here are the main methods, but still want to read the manual. To measure the voltage and the resistance and the basic multimeter, using the pen pen insertion holes
Not all the same with the clamp meter multimeter can measure resistance, voltage and current.Clamp meter is mainly to test current (especially large current) and design, so some clamp meter to measure the current only.
