Application of Digital Multimeter in Aviation Maintenance
The application of digital multimeters in aviation maintenance is because any circuit in the electrical and electronic system of the aircraft has a certain resistance value. In the process of use, the resistance value of each circuit will generally change. The purely quantitative change will turn into a qualitative change after a certain period of time. When the resistance value changes to a certain extent, the aircraft electrical and electronic system will not work properly. , or even malfunction. Therefore, by regularly measuring the resistance value of the circuit or equipment and mastering its changes, the faults of the circuit or equipment can be prevented and discovered in time. The limit of normal resistance value and abnormal resistance value (called critical resistance value) of a circuit or equipment is generally determined based on experience accumulated during measurement and with reference to equipment performance data, calculations, and experiments
