When a cycle is started, the analyser waits for the ending time of the first peak
and begins its peak detection between the starting time and the ending time. If a
peak is found, the peak that is detected and used for integration is presented in
yellow below the raw signal coming from the detectors.
During the cycle, the progress bar rises with time. The bar starts at the left and
ends at the right. The cycle length can be set in the
CONFIGURATION-
CYCLE
menu. During a peak, a green circle appears at the corresponding peak
of the upper grid alarm column (Al). When the peak detection process is
completed, the peak area is converted into the process value and displayed in
the grid beside the peak name in the value field. Then the analyser waits for
other peaks and applies the same procedure.
The cycle continues even if you exit the
