4.5.4 Signal Processing
There are three types of processing in the signal processing:
• Base level processing
The detector signal at a time set for base level processing within the analysis cycle
avoiding component signals is used as the base level value. If the base level process-
ing is not set, the detector signal immediately after the start of analysis is employed as
the base level value.
• Signal level processing
The differences between the detector signals at each time set for signal level process-
ing within the analysis cycle and the base level value, are used as the signal level
values. If more than one base level processing is set, the base level value immedi-
ately before a base level processing is used for signal level processing.
• Noise level processing
Among the preceding 20 data for detector signals at a time set for noise level process-
ing within the analysis cycle, the maximum and minimum values are used as noise
level values.
