A multimeter to measure voltage current of low voltage cabinet
Clamp ammeters referred to as clamp meter. The work is mainly composed of an electromagnetic current meter and bushing type current mutual inductor. Straight through current transformer core made of movable opening, and a clamp on ammeter, named. The utility model is a portable instrument which can directly measure the alternating current of the circuit without disconnecting the circuit, and is very convenient for use in the electrical overhaul, and is widely used.
Can measure the voltage, are equipped with a pen, the pen is inserted into the corresponding holes, transferred to voltage, can put the voltage to be measured respectively with two point pen, such as a live wire, a zero line.
Adjust to the current, and directly stick with the caliper to test the line of the current.Some clamp meter can measure voltage, some can not be measured voltage.
