  • Method and apparatus for converting a conventional DC multimeter to an AC impedance meter
    Patent number: 5248934
    Abstract: An R/Z converter for use with a conventional digital multimeter (DMM) provides enhanced capabilities of the DMM in measuring impedance and other functions where DC measurements are undesirable. The R/Z converter converts the test voltage of a conventional DMM into a square wave that is applied to the device being tested. The voltage from the tested device is seen by the DMM as an average DC value that is proportional to the impedance of the device.
