the start time for flow-paced routines when configured for
sample at start time in the Flow Mode configure option. Refer to
Figure 3-14. The diagram shows the sampler's response when
enabled or disabled at the start time for most basic and extended
mode routines.
Figure 3-15 diagrams the sequence of events preceding a routine
programmed for nonuniform clock times. Nonuniform clock time
programming allows you to enter a specific time and date for
each sample event. Samplers programmed with nonuniform
clock times may skip a number of samples if disabled for long
periods. If the sampler is disabled and subsequently enabled, it
will initiate only one event to compensate for the skipped sample
events even if several sample event times have been passed.
NOTE: Nonuniform clock time programming is designed to
replace flow pacing when a flow meter is not available at the site.
Before using a sampler programmed for nonuniform clock times
with a flow meter, be sure flow pacing is not a more appropriate
application.
The sampler will disregard the manual sample key during the
delay-to-start time and during the disable period. The periods
where the sampler disregards disable signals (Delay to Start)
and the manual sample key (when disabled) appear in Figures
3-14 and 3-15.
Start Time Delay – Entries made in the Start Time Delay con-
figure option affect the start times. The Start Time Delay section
discusses this configure option.
