When the process was out of control, it ran the risk of being out of specification, though, in this example, it did not pass the upper or lower specification limit ranges, meaning the process was within acceptable parameters for the customer. Why It Matters So, why is the LSL important ...
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 ...
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...
