I am trying to decide if the flex I/O Thermocouple module we have is bad.
I hooked a thermocouple to the module that we have in the main PLC 1756-L63. I configured it as a TYPE K and got a reading of 62.??. It reads within a couple of degrees of the Fluke thermometer that I had it attached to.
I plug it into the Flex I/O thermocouple module (Cat. No. 1794-IT8) and configure it as a type K and I get back 692+/-. Also, if I heat the sensor up and let it cool back down it won’t come back to the same reading, it may come back at 800+/- or some other reading.
Any thoughts folks?
