Earth Leakage Current Clamp Meter, 0.00mA-2000.00A

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 a clamp current meter?

The clamp ammeter is specially designed and manufactured for measuring AC leakage current. It adopts the latest CT technology and digital integration technology. It has the characteristics of small size, high precision and complete functions. Widely used in electric power, communications, meteorology, railways, oil fields, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields. The sensing iron core is made of a special alloy and adopts magnetic shielding technology, which is hardly affected by the external magnetic field, ensuring high precision, high stability and high reliability of uninterrupted measurement all year round. The high-precision clamp leakage current meter has an RS232 interface, and its software can be monitored online in real-time and historically inquired, dynamically displayed, with maximum, minimum, and average value indication, alarm value setting and alarm indication functions, and historical data reading, saving, Printing and other functions. The high-precision clamp leakage current meter can be used for AC line current measurement below AC600V, and online current measurement, and also has functions such as peak hold, data hold, and data storage. It is easy to use and is an essential tool for electrician safety testing.
