1、 - 1 - 题目: MF47 万用表制作 中 文 摘 要 关键词:万用表、电流、电压、电阻、表头。 万用表在电子测量中扮演着重要的角色,随着科技的发展,万用表的功能越来越多。 万用表可以测量电阻、直流电压、交流电压、直流电流,这是万用表最常用的功能。现 在的数字万用表又增加了许多新的功能,例如可以用万用表测量电容、三极管放大倍数、 二极管压降、元器件温度等;更有一种会说话的数字万用表,能把测量结果用语言播报 出来;还有的万用表可以通过 RS-232 接口,把不同时间下采集的数据传送给安装相关软 件的 PC 机,作相关时间分析等(例如 0I859CF) 。 我们所要组装的 MF47 型万用表主
2、要功能如下: (1) :直流电流测量 (2) :交直流电压测量 (3) :自流电阻测量 (4) :通路蜂鸣检测 (5) :音频电平测量 (6) :晶体管放大管放大倍数测量 (7) :电池电量测量 (8) :负载电压、负载电流参数的测量 (9) :标准电阻箱应用 英 文 摘 要 Keywords: multimeter, current, voltage, resistance, the table header. Multimeter in the electronic measurement plays an important role, with the development of t
3、echnology, more and more functions multimeter. Multimeter can measure resistance, DC voltage, AC voltage, DC current, which is the most common multimeter functions. Digital multimeter now added many new features, such as multimeter can measure capacitance, transistor amplification, diode voltage dro
4、p, temperature and other components; more of a talking digital multimeter, measurement results can broadcast out of the language; There are a multimeter can be RS-232 interface, the different time collected data to the PC, install the related software for the relevant time analysis (for example, 0I859CF). We want to assemble the main functions of MF47-type multimeter is as follows: (1): DC current measurements (2): AC-DC Voltage Measurement (3): gravity resistance measurement (4):
