I'm attempting to design an ohmmeter that can measure resistance from 0.01 to 10k Ohms. The circuit is based on the 4 wire Kelvin resistance measurement. So far the low end measurements are fine but I'm having difficulty adapting the circuit to measure from 10 to 10k Ohms.
How can I adjust this circuit to measure resistance from 0.01 to 10k Ohms? Thanks
