- Abstract:
- Application of the computer-controlled methods of measurements in laboratory exercises within the course "Measurements in Electrical Engineering" (MUE) is presented. In the experiment, which accomplishes the basic statistical analysis of the measurement results, a computer is used for processing the data obtained by the digital multimeter (DMM) connected to the computer, as well as for necessary calculations. Another experiment is used to test the response of different types of DMMs in measuring ac voltages. Thus, the computer serves as an ac calibrator supplying the chosen waveform to the measuring instruments by means of the D/A card. Both experiments are examples of virtual instruments developed on the basis of an ordinary personal computer (PC), equipped with the necessary hardware and software.
