Discovered mirrors needed to be cleaned
AGC scores-- Before cleaning: CO2_S:4937 H2O_S:-1500
After cleaning: CO2_S=2652 H2O_S=399.7
*protocol for cleaning mirrors is in the cabinet in downstairs lab
Then I zeroed and spanned:
Zero:
Before: CO2_S:13.8 H2O_S:-0.997
After: CO2_S:0.0 H2O_S:0.003
Span with 421.22ppm cal gas:
Before: CO2_S: 425.4
After: CO2_S: 421.1 (setting 0.998)
Span with 11.08C dew point:
