VERSATILE MULTIFUNCTION ELECTRICAL DIGITAL METER BASED ON PERSONAL COMPUTER

Luis Reyes Rosales Montero
  • Abstract:
    The objective of this work is to describe a versatile multifunction electrical digital meter based on personal computer; it has been developed for incorporation into a laboratory testing system. The meter uses two 12-bit A/D. The A/Ds are connected to parallel printer port of PC. The work was developed for Measurement of power. Using a programming language Turbo C++ was calculated: rmsVolts, rmsAmps, volt-amps, Reactive Power, Phase angle, frequency, Active power, watts-hour, resistance, capacitance and period. The values are shown at the monitor as a 4-digit display. The accuracy of meter is within 0.1%. The virtual power meter has a virtual two-channel oscilloscope. The meter was developed to senses power supply of electronic devices. (TV, PC) and electromagnetic device.
