Title: Calibration
Notes: Camilo Rey-Sanchez and Daphne Szutu Camilo cleaned the light-source leaf chamber (it wasn't too dusty) and attached it to this console for calibration. We connected the reference and sample inlet to the cal gases with a y-junction. Camilo had checked the zeros using the chemicals last week and found them unsatisfactory (we didn't write them down). We set the zero and the span using cal gas and dewpoint generator. Zero: Cal Gas (zero air), flow at 1SCFH: Before: CO2_S:~-15 CO2_R: ~-15 H2O_S: ~-2 H2O_R: ~-2 After: *All fluctuating around zero. Span with AMP 408.97ppm cal gas, flow at 1SCFH: Before: CO2_R: 413 CO2_S: 423 After: *Fluctuating around 409 Span with 16.0C dew point (2019-03-26), flow at 500 CC/min: Before: H2O_R: 17.50 C H2O_S: 18.52 C After: H2O_R: 16.00 C H2O_S: 16.00 C
