|---|---|---|---|---|---|
| 1461 | 2014-05-27 | Lab none | Calibration | Lab none | Trueppm = Probeppm*0.6676 + -1028; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 2238ppm, and 3056ppm. Ta=20.19C, P=101.3kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Madeleine. |
| 2008 | 2014-04-22 | Vaira 0 | Removed | Lab none | Removed from Vaira West profile at -4cm, replaced by sn K1310102 |
| 2020 | 2014-03-18 | Vaira CO2 probe West Profile -0.08 | Moved | Vaira CO2 probe West Profile -0.02 | At Vaira in the West profile this probe was moved from the -8cm location to -2cm |
| 2004 | 2014-01-29 | Lab none | Installed | Vaira CO2 probe West Profile -0.08 | West profile as -8cm with new U-shaped tops on the PVC enclosures. |
| 1441 | 2014-01-27 | Lab none | Calibration | Lab none | Trueppm = Probeppm*0.9255 + -857.4; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 3056ppm, and 10000ppm. Ta=22.7C, P=102.1kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Patty. |
| 1195 | 2014-01-24 | Vaira CO2 probe West Profile -0.08 | Removed | Lab none | Removed from Vaira west plot at -8cm for lab calibration |
| 1129 | 2012-03-21 | Lab none | Installed | Vaira CO2 probe West Profile -0.08 | Installed at Vaira in the west set at -8cm |
| 1413 | 2012-02-06 | Lab none | Calibration | Lab none | Trueppm = Probeppm*1.08 + 78.35; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 436ppm, 2238ppm, and 10000ppm (N2 bal). Ta=24.2C, P=101.5kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Siyan. |
| 1404 | 2012-02-03 | Lab none | Calibration | Lab none | Trueppm = Probeppm*0.9432 + -643; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 436ppm, 2238ppm, and 10000ppm (N2 bal). Ta=26.6C, P=101.6kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Siyan. |
| 1292 | 2010-04-06 | Lab none | Installed | Sherman Island | Installed at Sherman Island in Set A at -32cm. |
| 1357 | 2010-02-03 | Lab none | Calibration | Lab none | Trueppm = Probeppm*1.011 + -103.2; linear relationship between the ppm reported by the probe and the known ppm of the calibration tanks. Tanks: zero air (0ppm), 383ppm, 597ppm, and 2238ppm. Ta=24.1C, P=101.2kPa. Because the lab conditions were close to factory conditions, no temperature or pressure corrections were applied. Done by: Jaclyn. |
| 12 | 2009-12-01 | Factory | Repair | Factory | Vaisala factory repair and calibration 0-2% - certificate on file.
Problem: Got probe error 05, 10, and 11. No IR source and memory error. Action: Replaced probe circuit board and adjusted unit. |
