Comparison between a constructed arduino based system and Keithley SourceMeter 2400 on some electronics devices

Abstract

In this paper, a portable and cost effective arduino based system has been developed which measures the properties of the Device Under Test (DUT) by passing sweeping voltage across its terminals while measuring the corresponding current flowing through it. The system generates current-voltage data of the DUT and sends to a computer system for analysis. Also a comparison between the constructed arduino based system and Keithley SourceMeter 2400 on a resistor, Light Emitting Diode and BC548 transistor is presented. The constructed arduino based system effectively measures the ohmic value of the resistor, threshold voltage of the Light Emitting Diode, and the BC548 transistor’s threshold voltage with great accuracy.
