How to use clamp meter?

A digital clamp meter is an electrical tester that combines a voltmeter and a clamp ammeter. Like the multimeter, the clamp meteralso undergoes a digital process from the past analog to today.


The clamp meter is mainly composed of an electromagnetic ammeter and a penetrating current transformer. It is a portable instrument that can directly measure the alternating current of the circuit without disconnecting the circuit. It is very easy to use in electrical maintenance and it is widely used.

The clamp meter was originally used to measure AC current. Nowadays, the multimeter has all the functions it can use to measure AC and DC voltage, current, resistance, capacitance, temperature, frequency, diode, and continuity.

1. According to need, choose A~(AC) or A—(DC) file.


2. Press the trigger to clamp the clamp meter head into the current wire to be tested and hold it in the middle of the clamp head.

3, when the measured current is very small, its reading is not obvious, you can test the wire around a few turns, the number of turns to be the number of turns in the middle of the jaw, then the reading = measured value / number of turns.


4. During measurement, the conductor under test shall be placed in the center of the jaws and close the jaws to reduce errors.
