The final interface program is tested together with the system hardware. The data is then converted into its corresponding value and is written into a communication file. Verification is carried out by checking the values in the file against the calculated values. During simulation process, user applies voltage source to the system hardware, as well as obtaining measurements from the circuits or passive components. Testing is carried out by connecting a known resistor to the system hardware and then obtains the voltage level from the communication file.
Final testing covers the entire system in order to provide a feel of the overall presentation.
The purpose of this test is to finetune any minor presentation layouts such as a change of colour or typographical errors in the information. The hardware design consists of three passive components measuring meters, a data acquisition card and a test bench. The three measuring instruments are an ohmmeter, a capacitance meter and an inductance meter. They are meant for the user to verify the readings of the passive components. The following diagram illustrates the various input and output connections of the integrated RLC meter.
