| LI-7500A 0418 | 2017-07-02 | Lab none | Calibration | Lab none | Last calibration: 2017-06-21 AGC=97.9 SDM=1 DAC1=- DAC2=- Ambient P=100.37kPa, Tair=19.11C, Tdew=17.16C Zero Air at 1300psi, AMP CO2 513.22 at 350 Tdewspan=16.0 CO2 zero 0.8992 -> 0.8995 Offset: -2.76ppm CO2 span 0.9985 -> 1.0066 Offset: -0.12ppm H2O zero 0.8432 -> 0.8436 Offset: 19.4ppm H2O span 0.9806 -> 0.9847 Offset: 4.79ppm Notes: Large changes were seen on 6/13 after upgrading to 7500A. These were checked on 6/20 and 6/21 and the large changes were rolled back but apparently no configuration files were saved, so the last saved coefficients were the bad ones from 6/13 where CO2zero=0.9903, CO2span=1.0066, H2Ozero=0.8410 and H2Ospan=1.2209. The current cal looks good in comparison to the coefficient written down from 6/21. |
