Hi Ian,
I think Tamb is right. Since it is close to room temperature.
You are right. When I put my hand in front of TMP006, the result was around 30 degree. But in this test case, I did not put any thing in front of TMP006. What will happen if nothing is put in front of TMP006? From customer point of view, Tobj should be equal to room temperature. But unfortunately, I observed significant difference. What is your point?
If 6.4E-14 was used, the difference will be greater. This is reason that 8E-14 was used. S0 calibration is not my question.
Best regards,
Luo
