Calibration |
| Notes: |
Last calibration: 2025-06-02
AGC=100.1 SDM=7 DAC1=- DAC2=-
AIU sn AIU-2652, Presure A0=59.516, A1=15.503
Ambient P=100.4kPa, Tair=16.3C, Tdew=11.1C
Zero Air at 1800psi, AMP CA04396 417.61 at 1200 Tdewspan=14.00
CO2 zero 1.0844 -> 1.0844 Offset: 3.27ppm
CO2 span 1.0078 -> 1.0078 Offset: 4.33ppm
H2O zero 1.043 -> 1.0430 Offset: 6.5ppm
H2O span 1.0497 -> 1.0497 Offset: 14.63ppm
Notes: I reset the SS from 103.9 to 100 before calibration. This 7500 has a brand new base plate because the old one had corrosion inside on of the plug tubes. I didn't end up pushing the calibrations buttons this time - it was reading a little high and the internal chemicals might still be scrubbing.
