The Primary Variable Parameters screen provides details on the sensor, and advises the
current 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 allows 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.
