Re: SAE AMS 2750 rev E - Changes Matrix?
Acording to the requirement of AMS2750E, we calibrate the temperature controller by the three points method, it is necessary to include the following items in calibration report:
f.As found and as left data at each calibration point
g. Offset as found and as left (as required)
There are some kinds of condition to use offset or adjustment, i.e. adjust SAT ,adjust TUS and calibration instrument. if the offset field is zero ,when we calibrate it, itís OK, we do perform TUS for the this furnace after itís installed on furnace, TUS result is out of tolerance, in order to adjust TUS, a adjustment is input in offset field, then the TUS is OK. After 3 months, when we calibrate this temperature controller, if we donít remove the adjustment in the offset field, the calibration result will be out of tolerance, in this case, can you give me a example of calibration report ?
