Abstract: The paper describes the design of low-power digital multimeter based on MSP430F157. The system contains master-chip, the signal generating circuit, liquid crystal display circuit, keyboard input circuit and the corresponding measuring circuit, and it has many multi-range measurement functions, such as AC/DC voltage measurement, resistance measurement, capacitance measurement and transistor amplification measurement, and adjustable frequency sine wave or square wave output function. Furthermore, the system also extends humanity functions such as the automatic range switching, one minute free operation automatic sleep. After testing, the system can complete the measurement and the output task well, and it has ideal measurement accuracy and friendly interface.
