Operating Information (cont) Identification and Authorization Level The statistical view offers statistical data that matches with Total Quality management tools. Statistics is a tool to better analyze how a process behaves. The statistics are calculated from the data in the measurement file. - Page 4 Measurement Continuous Mode vs. Sample Mode • Stability: The stop criteria is met when the variation of the gas concentration is The continuous mode is typically used for process smaller than that entered in “Variation”. measurement, whereas sample mode is aimed at •...

The current measurement files are updated in volatile memory, and are regularly copied in A number of different interfering gas options are non-volatile memory (file back-up). At start up, the available (temperature, H O, He, O and H measurement files in volatile memory are updated...
- Page 8 Calibration General Modify Calibration Parameters We define 2 types of calibration: • the calibration of the gas to measure • the calibration of interferences To calibrate the gas to measure (main gas), the user usually puts the sensor in the main gas without any interfering gas.
