    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: Why need an earth leakage clamp meter?

    In any electrical installation, some current will flow through the protective ground conductor to the ground. This is usually called leakage current. Leakage current most commonly flows in the insulation surrounding conductors and in the filters protecting electronic equipment around the home or office.  On circuits protected by GFCIs (Ground Fault Current Interrupters), leakage current can cause unnecessary and intermittent tripping. In extreme cases, it can cause a rise in voltage on accessible conductive parts.
