Changes to SO2 instrument

Plumbed up SO2 cylinder to 10 sccm flow controller.
Now need to plumb standard add flow controller to three way add valve.
Changed SO2 sub-manifold flow rate from 5.o lpm to 8.0 lpm
- SO2 instrument pressure when sampling from PROPHET manifold at 5.0 lpm = 666 mmHg
- SO2 instrument pressure when sampling from PROPHET manifold at 8.0 lpm = 650 mmHg
- SO2 instrument pressure when sampling from sub-manifold at 8.0 lpm = 591 mmHg
-

Standard Add flow rate is: 1.5 lpm

SO2 calibration cylinder info:
Manufacturer: Scott-Marin
Cylinder #: CC106639
SO2 in Zero Air
4.87 ppmv +/-2% NIST
Made on: 12/20/2006

Added sequences for day and night Standard Add calibrations:
12 min cals
Starting at 14:24 LT
Starting at 02:24 LT
