Hi,
I want to take temperature measurements using a thermocouple and a data logger with analogue inputs, but I'm unsure whether it can be done with the set up I have. I have a 12 bit data logger that measures internal temp, pressure, etc. along with the following external ports;
I believe the resolution using the 0-3v port would be roughly 7uV, which would be around 5C change in temp, but when I connect it up and take readings I get no registered potential drop (I should at least get some increase/decrease in values shouldn't I). Does my data logger require greater sensitivity or should i just use another data logger? i don't have an electronics background so not really familiar with how this works.
Thanks for the help.

- 4 x analogue inputs (0-20mA, 0-3v, 0-10v, 0-24v)
- GND
- 3V supply
