Page 43: User Calibration Trouble Shooting
G200 Analyser Range OMG200N1.23 8.4 User Calibration Trouble Shooting Error Remedy User Zero failed A possible reason for this is that the instrument is trying to zero to a level which is outside the predetermined range set when the unit was calibrated at the factory. To rectify this, first ensure the unit contains absolutely none of the gas which is being zeroed by flushing thoroughly with nitrogen. -

G200 Analyser Range OMG200N1.23 Zero Calibration (Curve 2) This corrects the entire curve for lamp and filter variations caused by aging and user induced drift due to dirt etc. If done correctly there is often no need to complete a span calibration. However, a poor calibration[A] will result in a span error as shown with the zero indicating a small error [B] but a significant span error [C]. -
