The range can be adjusted manually, sine signal generator can adjust amplitude and frequency to improve accuracy, we measured the AC voltage through the ICL7650 to eliminate the error caused by the lower input resistance of AD637. Experimental results show that the performance of this design is stable and of high measurement accuracy.Key words: Voltage proportion method; 89C51; AD637; 1602 LCD;目录第一章 引言 1第二章 电压比例法测量原理 ...
