Title: Calibration
Notes: Partial calibration by Siyan. CO2 channel would not settle rising slowly. She used the CH4 standard that I had just checked from CO2 with the LI-6262. She also changed the internal chemicals removing factory installed bottles with a bit of each chemical in each. She replaced these with bottles filled by hand, single chemical in each.
