I am having an issue getting a IY4 to read my thermocouple correctly. We have a R type and K type hooked up and sitting at a known room temperature of 70 degrees f. We are using the correct CJC terminal block as described in the manual for the card. Our problem is that the feedback we are getting is no where near 70 degrees f. The K type reads about 30 degrees f lower and the R type 50 degrees off. We have checked all of the setting in the card and have verified that the thermocouples do work on an older 1769-IT6. Any help would be appreciated.
