All time points are relative to the start of the test. A time point of
000:10:00 allows for a sample to be taken 10 minutes after the start of
the test. If a second time point is entered as 000:25:00, the next sample
point is programmed 25 minutes into the test.
From the Timepoint Properties screen:
• Press Ok to accept the Time point information.
• Press Cancel to abort the process and return to the Method
Properties - Timepoints screen.
If sample point alarms have been enabled, time points are announced
via the Sample Point Alarm screen and an audible alarm.
From the Method Properties screen:
• Press Cancel to exit without saving the values and return to the
Select Method screen.
• Press Back to save all values to permanent memory and return to
the previous Method Properties screen.
• Press Save to save all values to permanent memory and return to
the Select Method screen.
NOTE
If a time point overlap is noted during time point entry, a warning icon
displays in the lower left of the Method Properties - Timepoints screen.
Time point overlap typically occurs when the manifold down lead time
plus the manifold down duration time exceeds the time point interval.
Press the warning icon to display the Timepoint Overlap Error screen
(“Timepoint Overlap Error” on page 110). The warning icon remains on
the screen as long as there are time point errors. A method can be saved
even it contains time point overlap errors.
WARNING
Methods that contain overlap errors do not execute properly.
