5 DATA PROCESSING 5.1 Average An average data is calculated by summing the measured values (momentary values) acquired every 1 second for a specified calculation period, and then dividing the cumulative total by the data counts. There are three AVERAGE data (AVERAGE 1 to AVERAGE 3), calculated using different calculation periods. And these calculation results can be checked on the respective AVERAGE screens.
5 DATA PROCESSING Q Average calculation The timing of average calculation start or end is based on the internal clock. If power shutdown occurs or if the internal clock is put forward: The momentary data during the power shutdown or the put-forwarded time period will be regarded as missing. If all the momentary values during the calculation period are missing, no average data will be recorded.
5 DATA PROCESSING 5.2 Integration A integration data is calculated by dividing the measured values (momentary values) acquired every 1 second by 3600 and summing these data for a specified calculation period. This calculation result can be checked on the INTEGRATION screen. The calculation period is 1 hour, and the data capacity is 1000 data. Note z If the data counts exceeds the data capacity, the oldest data will be automatically deleted.
5 DATA PROCESSING If the external integration reset is not performed after the time of the ongoing integration end + the waiting time for integration reset (3 min) : The integration result will be recorded at that time and then the integration value output will be reset to zero (integration reset). The internal clock will not be adjusted. If the internal clock is put back: The subsequent operation depends upon the corrected time.
5 DATA PROCESSING 5.3 Rolling Average The rolling average value between the current time and the 3-hour earlier point is sequentially displayed on the ROLLING AVERAGE screen as time passes. Fig. 46 ROLLING AVERAGE screen For the screen functionalities, see " Q Screens for data check" (page 31). Q Rolling average calculation The momentary value at that point is used for this calculation. If power shutdown occurs: The momentary values during the shutdown period will be regarded as missing.

10 APPENDIX 10 APPENDIX 10.1 Measurement Principle The ultraviolet absorption method is based on ozone's characteristic of absorbing ultraviolet rays of specific wavelength. In this analysis method, the sample gas which has passed through the filter is divided into two flow paths. The sample gas in one path is introduced to the deozonizer, where its ozone is eliminated, and then sent to the cell as “reference gas.
