Could you tell me how to use the caliper?
Clamp current meter has two kinds, one can only measure the AC current, capable of measuring AC and DC current, mainly used to measure the line current, other auxiliary functions can measure resistance, voltage etc..
Measurement methods: firstly, the jaw clamp ammeters clean (to ensure full, jaw anastomosis) and then estimate the current measured wire, the clamp ammeters stalls to proper position (if you do not know the measured current, the current position is adjusted in sequence from large to small, every adjustment must be table from the measured wire), then measured a wire into the ring opening on ammeter, current at the table shows that the measured conductor, in measure second and third respectively. At the same time as the two into the ring clamp meter, ammeter display is the current third wire. The three are placed in the table at the same value as zero (according to Gil Hof's law, flowing in or out).
The multimeter is also called the multiplex table, the multimeter, the three meter, the multiplication table and so on. It is an indispensable measuring instrument in the electric power and electronic departments. It is mainly used to measure the voltage, current and resistance. The multimeter is divided into a pointer multimeter and a digital multimeter according to the display mode. Is a multifunctional measuring instrument, multi range, general multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance and audio level, some parameters can also be measured AC current, capacitance, inductance and semiconductor (such as beta) etc..
