Simple Computer (PC) controlled data-acquisition board which enables to measure basic electrical quantities such as DC and AC (True RMS value) voltages and currents, resistance and frequency has been designed. The board contains all the necessary circuits for such measurements. Microcontroller on the board is connected with PC by a serial channel, so it is possible to set the measuring conditions from the PC and to read the measured results on the PC monitor. The program for system control and calculations is written in assembly and C.
