SAT (System Accuracy Test) temperature according to AMS2750E

[Resar]

Hello,
At the company where I work we are preparing for the Nadcap heat treatment audit. But I do not quite understand some of the AMS2750E requirements regarding the SAT.

3.4.5.1 The displayed temperature indication and/or recording of the sensor being tested as used in production, with appropriate offsets or correction factors, at any operating temperature, shall be compared with the corrected temperature indication of the test sensor on a test instrument.

English is not my native language and maybe this is the problem. For me, the question is in the interpretation of the expression "any operating temperature". Does it mean only one temperature or every one temperature from the qualified operating temperature range.

Thanks in advance.

3.4.5.1 is stating that unlike a TUS (Temperature Uniformity Survey) the temperature of an SAT can be any temperature in the range your oven is certified for.

AMS2750F was released about a month ago, and in it they changed that line to make it more clear.

3.4.7.1 The displayed temperature indication and recording of the sensor being tested as used in production, with appropriate offsets or correction factors, at any temperature within the qualified operating temperature range(s), shall be compared with the corrected temperature indication of the test sensor on a test instrument.
