Many thanks. Yes, it is now obvious. I intended using 3 separate constant current sources which would have involved a PSU and significant component count. The recorded data is processed off line. I intend keeping the simple series circuit and solving the network to yield the 3 resistance values, and...

Hi,

Please find attached a sketch wiring diagram.

Is there an equivalent input circuit for the differential mode please?

Thanks for your interest.

I have a ADC20 with terminal board. I am attempting to measure 3 temperatures using thermistors. I have wired them in series with a 10k precision resistor and fed the circuit from the 2.5v on the terminal board and grounded the circuit at (AG) I connected each component to inputs (1-2), (3-4), (5-6)...
