| GP-001 GP20140021 | 2017-02-22 | Lab none | Calibration | Lab none | y = 13.36*x The probe was tested against a new probe with decreasing CO2 from 2.4% to zero. This probe read significantly lower than the standard probe and showed some lag at higher change rates. |
| GP-001 GP20150109 | 2017-02-22 | Lab none | Calibration | Lab none | y = 19.2*x
It was determined in the lab that the high power draw was due to a bad cable and not the probe. The probe was tested against a new probe with decreasing CO2 from 2.4% to zero and no significant offset was observed. |

| AM25T 4852 | 2017-02-21 | Factory | Calibration | Factory | Calibrated by Campbell. Good for two years. |
| AM25T 4852 | 2017-02-24 | Factory | Returned | Lab none | Returned from Campbell after repair for: 12V screw terminal damage, internal thermistor damage. Campbell says: Able to verify customer problem. Replaced terminal connector (P22C) 12V connector. Replaced internal thermistor (Z16) due to leads being broken off. Bench tested unit, calibrated unit with documentation, final tested to verify correct operation. |
