Last calibration: 2023-05-21
AGC=102.4 SDM=7 DAC1=- DAC2=-
AIU sn AIU-2652, Presure A0=59.516, A1=15.503
Ambient P=100.3kPa, Tair=21.3C, Tdew=10.9C
Zero Air at 1900psi, AMP CA04395 417.61 at 1300 Tdewspan=16.0
CO2 zero 1.0837 -> 1.0844 Offset: 1.46ppm
CO2 span 1.0058 -> 1.0078 Offset: -0.13ppm
H2O zero 1.0414 -> 1.0430 Offset: 7.7ppm
H2O span 1.0280 -> 1.0497 Offset: -0.44ppm
Notes: I also got the original config file from Licor that had a date of 2020-01-28 and coefficients: CO2 zero 1.0837, CO2 span 1.0057, H2O zero 1.0420, H2O span 1.0367. Seemed like very stable robust calibration - no problems.
