Calibration |
| Notes: |
Last calibration: 2016-12-05
AGC=58 SDM=7 DAC1=0-1000 DAC2=10-25
Ambient P=100.46kPa, Tair=19.9C, Tdew=5.83C
Zero Air at 1750psi, God CO2 421.22 at 400 Tdewspan=16.00
CO2 zero 1.0707 -> 0.9573 Offset: -519ppm
CO2 span 1.0029 -> 1.0037 Offset: -0.22ppm
H2O zero 0.7391 -> 0.7394 Offset: -1.3ppm
H2O span 1.0255 -> 1.0063 Offset: 0.41ppm
Notes: Something happened to the CO2 coefficients after the last calibration causing the CO2 channel to be way off. New calibration seems good and matches historic coefficients.
