1. A digital clamp meter is a portable electrical measuring device with a clamp-like shape that can be used to measure AC and DC voltage and current. It features a digital display for quick reading of measurement results. 2. Autoranging amperage voltage testers are a special type of digital clamp meter. It has an automatic range function, which can automatically select the appropriate range according to the size of the measurement signal, making the measurement easier and more accurate. 3. The tester is capable of measuring AC and DC voltages. AC voltage refers to the continuously changing voltage in the power supply or circuit, and DC voltage refers to the constant voltage in the power supply or circuit. Using this tester, users can accurately measure both types of voltage values. 4. In addition to voltage measurement, the digital clamp meter automatic range ampere voltage tester can also be used to measure current. The user only needs to wrap the wire of the circuit under test on the jaws of the pliers, and the tester will display the current value passing through the circuit. 5. The digital clamp meter automatic range ampere voltage tester is very convenient to use. It features an intuitive operator interface and an easy-to-read digital display, allowing users to simply place the test fixture on the circuit under test to obtain accurate voltage and current measurements. This makes circuit troubleshooting and electrical equipment repairs more efficient.
