自从1971年微处理器(以下简称μp)问世,几年后当其在价格上降到可取时就很快应用到各种电子测量仪器中、数字多用表(以下简称DMM)是最早装入μp的电子测量仪器之一,1975年生产出第一种装入4位μp的DMM,不到十年的今天,8位μp和片级μc在DMM中已达到如此广泛的应用。大大地促进了DMM的智能化和系统化,使仪器能自校、自检、自诊和进行各种运算以及其他功能,配上接口极易组成灵活的测试系统。常用于数据采集,ATE及其他工业用系统。
Since the advent of the microprocessor in 1971 (hereinafter referred to as μp), a few years later when its price dropped to the desirable when quickly applied to a variety of electronic measuring instruments, digital multimeter (hereinafter referred to as DMM) is the earliest loading μp One of the electronic measuring instruments, produced the first 4-bit μP DMM in 1975. Less than a decade ago, 8-bit μp and chip-level μc have reached such a wide range of applications in DMMs. Greatly promoted the intelligent and systematic DMM, so that the instrument can be self-school, self-test, self-diagnosis and a variety of computing and other functions, coupled with the interface can easily form a flexible test system. Commonly used in data acquisition, ATE and other industrial systems.
