hhhmmm ohms please help

how to get a 3 wire led display like this http://www.amazon.co.uk/0-100V-3-Wire-3-Digit-Voltage-Voltmeter/dp/B00EZ5298M/ref=sr_1_22?ie=UTF8&qid=1382255514&sr=8-22&keywords=3+wire+led+display to show ohm instead of voltage

  • Sorry - there isn't quite enough information on the Amazon site to help you here. Taken at face value the meter's range is 0  - 100V and that isn't sutiable for measuring resistance. Internally the meter won't really need 100V for full scale - probably more like 1V so there will be an atttenuator inside it. It may be possible to modify the meter so that its range is more useful. You will still need some additional components (op amps etc to make it read resistance).

     

    If you are just looking for low cost then buy a cheap multimeter.
