I have 2 four channel thermocouples attached to a Vint hub. How Do I loop all the channels sequentially to check variables? Thanks.

I have a couple of membrane potentiometers that I’ve hooked up to the ADC, as the variable resistor in a ‘single active element’ Wheatstone Bridge circuit. I’m seeing considerable drift in the reported resistance, it is still rising logarithmically after 30mins+, at a fixed wiper point approximately...

I using a 1046 board to measure the resistance of linear potentiometers (10kohm and 20kohm) in a wheatstone bridge setup. However i notice that readout value will tend to drift a mV/V or two (on a range of 400-450mV/V). Can anyone think why? Referring to the example circuit* what are the +5v and GND...
