Last calibration: 2022-12-05
AGC=100.7 SDM= DAC1= DAC2=
Ambient P=99.8kPa, Tair=18.7C, Tdew=6.3C
Zero Air at 1300psi, AMP CA04119 524.77 at 1150 Tdewspan=16.00
CO2 zero 0.9145 -> .9149 Offset: 2.13ppm
CO2 span 1.0433 -> 1.044 Offset: -.33ppm
H2O zero 0.8933 -> .8913 Offset: -12.8ppm
H2O span 1.0381 -> 1.0275 Offset: .22ppm
Notes: Had to use 524.45 as "span point" for sensor to read 524.77 after spanning. I didn't really notice this for other sensors I calibrated today but I'll need to pay more attention next time. Previously, there was a large offset in CO2 span. Need to keep an eye on this sensor.
