I suppose . . . if all of the temperature sensors show an increase except T_Glassin, that sensor might be malfunctioning. But I doubt it. When a sensor malfunctions it generally drifts, or it shows zero, or some random number. It does not usually show the same value it did during calibration. In this case, if the thing is malfunctioning it is too low. Meaning it drifted down. It should keep going down, lower and lower. This is not good news. In calorimeters of this general design that I know of, such the ones Mel Miles made where he measured the temperature at the cell wall, temperatures everywhere rise when heat increases. They may not all rise the same degree, but they rise proportionally. You do not see one sensor showing the same temperature as before. I have no idea why it might be doing this, but it does seem like an artifact. As I said before, the highly stable output that turns on right away also makes me think it is an artifact. - Jed
