    Thermocouple errors

    Solved At least, I think so, subject to more extensive testing. I'm feeling a little bit sheepish, though I don't think it was entirely unreasonable of me to expect that the 4 things labelled as thermocouple outputs would be, well, thermocouple outputs (moan); but it turns out that channels 3...

    Thermocouple errors

    Given that the problem is consistently happening on the two channels and not appearing at all on the other two, I'd guess it's probably more likely to be the switches rather than the plate? If it's due to an error with the reference temp would you expect the errors to change if the logger is at...

    Thermocouple errors

    Thanks for all the suggestions - I've narrowed it down, sort of. I'm still no wiser as to the actual problem, but now I've managed to replicate the problem in the lab as well. I have four thermocouples, going into channels 2, 3, 5 and 6 on the datalogger. The thermocouples on channels 2 and 5...

    Thermocouple errors

    On further investigation, it seems to be some sort of interference between the different thermocouple channels, but I'm not sure why, yet.

    Thermocouple errors

    Hi, I've set up a temperature measurement rig for a project measuring the temperature of various indoor and outdoor temperatures, for a building physics investigation, and I'm getting some strange errors. The system works fine in the lab, and seemingly fine at one site, but at another site it's...
