Adjust purity monitor alarm ranges, add new calculations
slow monitoring and control
Changes requested by Ben Carls per review committee recommendations:
- Turn the age of data from a MAJOR alarm to a MINOR alarm, warranting an email only.
- Change minor alarm threshold to 6 hours. (No major alarm.)
- Create an alarm for QA/QC from the long purity monitor:
QAQCRATIO = ANODETRUE / CATHTRUE
Initially, an alarm should go off if the ratio goes below 0.391.
