Development of Intelligent Digital Multimeter
Existing digital multimeters have problems such as long measurement time, low automation level, and inconvenient operation. Aiming at these problems, the design method of automatic test is proposed, the software and hardware components of the automatic test system are introduced, the process of the automatic test system to complete the test is expounded, and a new type of intelligent digital multimeter is developed accordingly. The meter can automatically identify the measured physical quantities such as voltage, current and resistance, and automatically measure them. Its measurement accuracy meets national standards, and it has the advantages of short measurement time, accurate data, high degree of automation, strong practicability, high reliability, and small size. The advantage is that it is a modern intelligent instrument. Compared with the traditional digital multimeter, it improves the test efficiency and the accuracy of the test results, avoids the influence of human factors, and ensures the test accuracy. The watch is low in cost, easy to use, and has wide application prospects.
