Does anyone use a "single point check" to verify the output of their thermocouples and RTDs (basically checking to make sure the element is reading something), then use a TC/RTD simulator to check the rest of the loop? Everything I've read indicates that RTD's drift, and thermocouples drift...
Some people at work are suggesting the use of single point calibration in-place to calibrate our thermocouples/RTDs, and prevent damaging them through removal. Others are saying that this isn't effective because it doesn't give you at least one other point to set 0-point and span. Does anyone...
