I am using a TC-08 data logger with Type K thermocouples in a cooking experiment. The griddles is set at 150C and I cook to an internal temperature of 60C. I am getting sporadic readings as if I were using a bad thermocouple. However, this happens on both of my data loggers with new thermocouples so I donâ€™t think it is the thermocouples or data logger. Interestingly, if I have a thermocouple in channel 1 & 2 and have them on the same piece of meat the readings are steady, if they are in separate pieces of meat the reading become sporadic. Any ideas about what is happening or how I can fix this problem?
