so your IR thermometer is/was correct from the start and the thermocouple is not actually needed? Interesting! Am I correct in guessing that the Tcase to Tjunction gradient is increasing as the junction temperature rises from 40C --> 90C?
For example:
Tcase temp: 30 40 45 50 55 60 65 70 74
Tjunct temp: 31 42 50 58 66 76 84 95 100
Gradient ~: .01...2...5...8..11.16.19..25.27
Is this a close scale?
