Leakage Current Clamp Meter, 0.0mA-60.0A AC/DC

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 measure leakage current?

Clamping the meter around the line and neutral conductor of each circuit, and will measure any current imbalance – which is the leakage current – and show it directly in milliamps. Alternatively, you can clamp the meter around the incoming tails of the consumer unit/panel, then switch off all the MCBs. If you switch the MCBs back on one at a time, you’ll be able to see the leakage current associated with each circuit. The sisco leakage current meter is a very good clamp meter to choose because it can also measure AC currents up to 60A, so you’ll find many more uses for it in addition to earth leakage testing.
