Automatic Measurement of RC Circut

This paper is concerned with the automation test and measurement of RC circuit charging and discharging using Thurlby 1906(TTi1906) multimeter, interfaced with personal computer(PC). The communication between the TTi1906 multimeter and the PC are made through the RS232 controller using the serial COM port of the PC. The processes are controlled by a software written in Qbasic language and assembled on the PC. The software of RC charging and dischanging has been designed and tested successfully. The software of RC charging and discharging has been designed and tested successfully. The software simulation gives an accurate and actual result of the output voltage where the tolerances of components are taken into consideration. This software offers several advantages over manual measurement such as faster and efficient, easy to use, reliable and can be extended to serve other applications. [Authors' abstract].
