I'm trying to design a simple circuit to measure resistances between 100 and 100k ohms. I'm a tad rusty with electronics but what I've tried so far are a standard voltage divider and an attempt at a constant current source using an LM317 regulator. Neither circuit seems to reach a range vs accuracy sweet spot. Can anyone suggest a circuit that might serve me better? Ideally I would be able to adjust the accurate range using a voltage between 0 and 18 volts however if I have to adjust current output with different resistor values that's fine. The LM317 works this way however I can only really measure between 1-100 ohms with that circuit.
