  • Patent number: 6556003
    Abstract: With added circuits and the computer's existing internal circuits and devices, a PC can function as a multimeter for those users who are testing, designing or analyzing an electronic device, which requires the features of a computer and a multimeter. This invention provides much convenience to the user and will reduce or eliminate the cumbersome handling of two pieces of equipment on the same workbench. The PC multimeter utilizes some of computer's existing devices, such as output devices, input devices, microprocessor and memory, also includes additional multimeter specific circuits assembled on a PCI or ISA I/O board which is installed in the PCI or ISA expansion slot inside the computer. Two test leads are the only elements connected to the I/O board and extruding outside of the computer.
