1. Working principle
Based on the principle of electromagnetic induction and the Hall effect. When the jaws of the clamp meter are clamped on the circuit under test, the magnetic field generated by the circuit under test will induce an electromotive force inside the clamp meter, which will be further processed by the Hall element, etc., so as to accurately measure the current, voltage and other electrical parameter signals in the circuit.
2. Functional characteristics
Current measurement: It can measure AC and DC current in real time. The measurement range usually ranges from 0A to thousands of A. Some high-precision models can reach an accuracy of 0.5A or higher. It can meet the current measurement needs in different scenarios, such as detecting line current during power equipment maintenance.
Voltage measurement: It can measure AC and DC voltage in real time. The range is generally 0V - 1000V, and the accuracy can reach 0.5V or higher. It can be used to detect whether the power supply voltage is normal, etc.
Power measurement: It can measure active and reactive power. The range is usually 0W - 1000kW, and the accuracy can reach 0.1W or higher, which helps to evaluate the power consumption of electrical equipment.
Phase measurement: It can measure the phase difference of three-phase circuits, which is convenient for fault diagnosis and maintenance. It is very practical in the commissioning and maintenance of three-phase power systems.
3. Product features
Non-invasive measurement: No need to disconnect the circuit, just clamp the measured wire with the jaws to measure, which does not affect the normal operation of the circuit, and is convenient and safe to use.
Intuitive display: The digital display screen can clearly and intuitively display the measured value. Compared with the traditional analog pointer clamp meter, the reading is more accurate and convenient.
High precision: Using digital technology and advanced sensors, the measurement accuracy is high, which can meet a variety of professional measurement needs.
Good portability: Small size, light weight, easy to carry, suitable for various field measurement work.
