What is the current clamp? What are the main points on ammeter selection?
The true effective value of non sine wave switching power supply outside of a sine wave (True RMS). The products were selected: 1: point clamp meter object detection based on the detection of object, different alternating current, direct current, or to choose the type of leakage current; maximum conductor size 2: can be detected with the detection sites, testing whether it is necessary to use the average value of the circuit on ammeter circuit and transformer can not correctly detect the motor and other non sine wave from 21mm to 53mm in diameter diameter of different kinds of.3: value. The true effect detection circuit should use the true RMS clamp ammeters.4: other functions can not only detect the current, as well as detection and recording output in one of the models.
Simple operation, do not need to test large current circuit can be directly connected. Safety clamp meter, multimeter and insulation resistance meter are analogue and digital two. The detection range of the standard type: AC, DC from 2A to 200A or 400A, also can be detected by 2000A high current products leakage detection; micro current detection and product number mA and the detection of transformer power supply
Clamp ammeters also called clamp table, Taiwan more named hook table. Clamp meter is clamped in the wire, cut off the circuit state, current detection convenient testing instrument (also known as nondestructive measurement). Analog pointer multimeter and digital multimeter is current detection circuit is cut off, and the clamp meter just caught in the electric wire sheath, current can be detected.
