Instruction Manual

748374-F March 2003

From the Analyzer Diagnostics menu, all ana- lyzer health diagnostic information can be ac- cessed. Calibration controls are also accessible from this menu.

The Primary Variable Parameters screen pro- vides details on the sensor, and advises the cur- rent status of the sleep mode. If the oxygen concentration exceeds 100 ppm, the sleep mode timer begins counting. At the end of 45 minutes, if the concentration has not dropped below 100 ppm, the Analyzer Module will go into sleep mode to protect the sensor from damage due to high oxygen exposure.

The Advanced / Expert Calibration menu al- lows access to user calibration screens, and the factory calibration data screens for viewing and data entry. The Gas Scale Factor menu is also accessed from this menu.

It is not recommended to conduct user zero and span calibration functions since the sensor is factory calibrated and does not exhibit detect- able degradation of calibration over time. The risk of erroneous calibration due to inaccurate gases is greater than the potential of factory calibration change.
