    The wireless clamp meter measures AC current to 1200 amp, and the jaw size is Φ48mm. The wireless clamp current meter can replace the high and low voltage transformation ratio tester, that is, measure the high and low voltage currents of the primary circuit and the secondary circuit respectively, and then calculate the high and low voltage transformation ratio. The insulation rod is light and has the characteristics of moisture resistance, high-temperature resistance, impact resistance, bending resistance, and high insulation.

    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: How does a clamp meter read?

    • Select gear and range. Turn the meter switch to the DC current "mA" position, and select the correct range according to the measured current. If the current is not known, in order to prevent the current from being too large and exceeding the range, you can first place the DC current at the highest gear for testing. If the range is too large, then reduce the range until the range is appropriate.
    • Connect the circuit in series. When the multimeter measures current, the test leads must be connected to the current in series, and the red test lead is connected to the high potential end of the circuit, and the black test lead is connected to the low potential end of the current.
    • Reading method: 1. Correctly select the scale line for reading. 2. Converted current value: Current value = the number of scales pointed by the pointer × the size of the range / the maximum value of the selected scale.

    The large digital display is clear and easy to read
    The wireless functionality is a convenient feature, allowing me to take measurements from a distance and even view the data on my smartphone or tablet via a dedicated app. The clamp design is practical and makes it easy to measure current in various situations, especially in tight spaces where traditional meters might struggle. The large digital display is clear and easy to read, which is a plus.
