本设计电阻测量是利用A/D转换原理,将被测模拟量转换成数字量,并用数字方式显示测量结果的电子测量仪表。通常测量电阻都采用大规模的A/D转换集成电路，测量精度高，读数方便，在体积、重量、耗电、稳定性及可靠性等方面性能指标均明显优于指针式万用表。-This design resistance measurement is the use of A/D conversion principle, to analog conversion to digital quantity being measured, the measurement results with digital display electronic measuring instrument. Resistance measurement usually USES the mass of A/D conversion of integrated circuit, high accuracy, easy reading, in the size, weight, power, stability and reliability indices were significantly better than that of the pointer multimeter.
