Abstract

Capacitance measurement with integrated instruments (function generator & Digital multimeter) has been designed and developed. The unknown capacitance is measured by measuring the voltage across capacitor in RC network. The Digital Synthesis Arbitrary Function Generator/Counter (Protek 9305), and Dual Display Multimeter (Escort 3146A) are used as part of instrumentation. The function generator and digital multimeter instruments are available in all the labs, by integrating these devices a powerful yet cost effective instrumentation can be evolved. This paper describes such an instrument for capacitance measurement. MATLAB program interfaces the instruments through serial port and collects data, the applied and measured voltage at particular frequency, the results are analyzed to get corresponding Capacitance of the any capacitor under test. The present system will be of great use in industrial environments as well as for engineers in the industries and researchers in organizations.

电容测量集成仪器

设计开发了函数发生器和数字万用表集成电容测量仪器。通过测量RC网络中电容两端的电压来测量未知电容。数字合成任意函数发生器/计数器(Protek 9305)和双显示万用表(Escort 3146A)用作仪器仪表的一部分。所有实验室都有函数发生器和数字万用表仪器，通过集成这些设备，可以开发出功能强大但成本有效的仪器。本文介绍了一种用于电容测量的仪器。MATLAB程序通过串口与仪器接口，采集数据，对特定频率下的外加电压和被测电压进行分析，得到被测任一电容对应的电容值。本系统不仅适用于工业环境，也适用于工业中的工程师和组织中的研究人员。
