CALIBRATION
4.1.2 Diagnosis of the MSRS Sensor Status - Screen pages 3.2.4 to 3.2.7
While the control gas passes through the analyzer after a calibration sequence, the
MSRS sensor status is diagnosed to assess the working order of the analyzer.
The system compares the theoretical and measured concentration of the control gas.
To begin this diagnosis complete a calibration sequence (see Section 4.1.1). When the
calibration is over, screen page 3.2.4 will appear.
Alternatively if the reading was stable and the calibration was forced from screen page
3.2.3 by pressing the
VALID
key, then screen page 3.2.4 will appear.
