Yield Improvements Through Comparing LSL and USL Take some time and compare where the upper and lower specification limits compare with the mean. If you see a shift, where one specification limit is much closer to the mean, and one is much farther away, you may have an opportunity to adjust...
Re: compute six sigma when the USL LSL are varying Miner said: You have to be very careful of the context in which sigma is used. The context to which you refer is sigma as meaning standard deviation of the process, in which case you are correct. However, the term process sigm...
calibrated range” or “calibration range”. That is, at what input shall the transmitter analog output be 4 mA; Lower Range Value (LRV) often referred to as “zero” meaning 0%, and at what input shall it be 20 mA; Upper Range Value (URV), sometimes called “full scale” meaning ...
