A measuring instrument of little resistance by using C8051F005 chip microcomputer
(China University of Mining & Technology, Jiangsu Xuzhou 221008,China) Abstract: This paper presents the measuring principle and design of a new portable measuring instrument of little resistance, including its design of hardware and software. The ultralow-power C8051F005 produced in CYGNAL Corp has been as the core of this system, and so this instrument can complete data memorizing, communication, LCD displaying and other functions. Lower power-consuming, high accuracy and portable are all its peculiarities. So in particular it can be properly used in work field besides in the lab, the data sampled can be saved in the microcomputer and transferred to computer, data processing can be done by computer.
