    Hi All,
    I have a project to do which is a Digital Multimeter.
    It must be capable of measuring Voltage, Current and Resistance.
    It must also feature a 3 1/2 digit display.

    I have been thinkin about basing it around the 7106 IC.

    My problem is that i am totally lost.
    I would be greatful if anyone had or could point me in the right direction of some basic schematics.
    Any other help or info would be greatful.

    Kind Regards

    The complete schematic for making a digital voltmeter is in the datasheet of the ICL7106.
    Then use Ohm's Law to let it measure current and resistance.

    Hi again, posted a different thread by a mistake. Im looking for help with ISIS and ARES now.
    Does anyone have a DMM circuit done out in ISIS or ARES?
    I cannot find a suitable display in the ISIS library.

    Thanks Again
