Anyone using Siemens CentraLink for qc?  I’m having trouble understanding how to set up the qc.  i understand the target is the mean but i don’t get the deviation part.   The instruction manual says to enter 1 but that makes the range too tight and 2 makes it too wide when compared to the manufacture ranges.   Any help would be appreciated.   Thanks in advance 

We had a representative from CentraLink set ours up at first- I think that was a part of the service they offer.  Then they did a web call to go over it with us.  They are very helpful and have been with any questions since then.
