of the peak number, in which the latest analysis has been executed.
The system uses dashes “-” to connect the stream number, peak number and
peak name in sequence, followed by the concentration unit (%, ppm or no unit) in
parentheses.
Date/time Indicates the date (year/month/day) and time (hour/minute) when the analysis for each
cycle started (up to 250 date/time data items). If the number of data items exceed 250,
the oldest data item is discarded to make way for a new data item.
