The following four types of measurement (check items) can be set as a trigger of a Component
alarm. One check item can be set for each contact.
• Concentration
• Retention
time
• Variation coeffi cient
• Tailing factor

 Timing
The Timing function of D/O is a function to send information about the time of completion of peak
detection to the upper systems.
This is used in combination with analog hold output (analysis result output) that uses A/O.
The contact output is turned On and Off at the time set for the D/O operating time in the SYS
method.
 Calibration/Validation
The Calibration/Validation function of D/O is a function to send out information that a calibration
or validation number set for each GCM is being executed. The contact output is turned On when
the measurement status of the GCM set on the D/O setting screen is the status of the specifi ed
calibration or validation number.
Multiple calibration or validation numbers can be set for one contact.
