Built 20k span ohm meter with ICL7106

[GKM]

HI, I  search for a circuit schematic for built a 20k span ohmmeter with a ICL7106.

Does someone have a link?

Use your imagination.

The ICL7106 is a volt meter IC. A resistance can be converted into a voltage by passing a constant current though it. If you aim for 200mV as the full scale which represents 20k (the decimal place can be adjusted manually) then the desired current can be calculated using Ohm's law.
