In the process of repairing cars, people use digital multimeters frequently, which can provide accurate diagnosis basis for car repairs. The characteristics of the digital multimeter make it widely used in the field of automobile maintenance. For the measurement of resistance, current and voltage, the digital multimeter can realize it. However, in the process of detection, due to the influence of various reasons, it will cause different degrees of damage to the relevant electronic components in the car circuit. Therefore, when measuring the automotive circuit, it is necessary to use a dedicated instrument, pay attention to the various measurement processes, and provide a basis for the accuracy of the measurement. In this article, the author gives a basic introduction to the digital multimeter, and then studies the application of the digital multimeter in the measurement of automotive circuits.
