There is a problem with second TC (thermocouple) reading: it is off by couple degrees or some mV. I've already edited this issue while troubleshooting, and so far the only problem left is this voltage difference. With detached TCs, readings are ~150 mV from 1st TC end analog input, and ~250 form the second. I did not calculate schematics parameters, I just followed ADS datasheet blueprint for RC part and this github project for arduino, and electric part is not my strong point so I am a bit at loss here. Is it supposed to have voltage difference and therefore temperature difference by some degrees, or the datasheet schematics themselves are bit off?
