【 摘 要 】

This paper focuses on the research and development of high-precision measurement instruments based on ARM, which is a kind of AC(Alternating Current) and DC(Direct Current) resistance measuring instruments for cables and wires. The instrument has a good human machine interface, can automatically collect data of temperature, voltage and other parameters through sensors. After the collected data is transmitted to the CPU for processing and calculation, the resistance, inductance, phase angle are obtained and displayed on the screen.The instrument has the ability to automatically switch ranges, perform complex calculations and automatically compensate for errors, and can flexibly change functions and expansion modules for use in electronics and industrial applications.
