Flexible Clamp Meter, 0.00A~9999A AC

Q1: What is clamp ampere meter?
A1: A clamp ammeter is a combination of a current transformer and an ammeter. The iron core of the current transformer can be opened when the wrench is tightened; the wire through which the measured current passes can pass through the gap opened by the iron core without being cut off, and the iron core is closed when the wrench is released.

Q2: How does a current clamp meter work?
A2: A clamp meter is a clothespin-shaped instrument that can be clamped around a live wire in order to measure the current it's carrying. As a measurement principle, clamp meters detect the magnetic field emitted by current flowing in a wire in order to measure the current value.

Q3: How to use a clamp ammeter?
A3: When using a clamp ammeter to detect the current, be sure to clamp a measured wire (wire). If two (parallel wires) are clamped, the current cannot be detected. In addition, when the center (core) of the clamp ammeter is used for detection, the detection error is small. When checking the power consumption of home appliances, it is more convenient to use a line splitter. Some line splitters can amplify the detection current by 10 times, so the current below 1A can be amplified before detection. Use a DC clamp ammeter to detect the DC current (DCA), if the current flows in the opposite direction, it will display a negative number. This function can be used to detect whether the car's battery is in a charging state or a discharging state.

Tips: What is the function of a clamp meter?

A clamp ammeter is a combination of a current transformer and an ammeter. The iron core of the current transformer can be opened when the wrench is squeezed; the wire through which the measured current passes can pass through the iron core. The measured circuit wire becomes the primary coil of the current transformer, and the current is induced in the secondary coil current.

Usually, when measuring the current with an ordinary ammeter, it is necessary to cut off the circuit and shut down the circuit before connecting the ammeter for measurement. This is very troublesome, and sometimes the motor in normal operation does not allow this. At this time, it is much more convenient to use a clamp ammeter, which can measure the current without cutting off the circuit.
