Calibration |
| Notes: |
Last calibration: 2023-01-04
AGC=101.5 SDM= DAC1= DAC2=
Ambient P=100.6kPa, Tair=24.9C, Tdew=10.8C
Zero Air at 1300psi, AMP CA04119 524.77 at 1150 Tdewspan=16.00
CO2 zero 0.9187 -> .9207 Offset: 7.69ppm
CO2 span 1.0187 -> 1.0176 Offset: 0.83ppm
H2O zero 0.9029 -> .9001 Offset: -17.3ppm
H2O span 1.033 -> 1.0105 Offset: .47ppm
Notes: Offsets are recorded using the 2023-01-04 calibration as the starting config file. Attempted calibration on 4/7 but the H2O zero offset was -38.3 after needing a long time (45+min) to stabilize. The H2O span offset never stabilized. I decided to swap the chemicals then and this is the first calibration since chemical swap.
