After you've completed the entries for the first bottle group, the
sampler will present the following message:
-- BOTTLES, ----- ml
This message marks the beginning of the second section. It
reports the number of bottles allocated for the second bottle
group and the total volume of their combined capacity. The
sampler displays this information to help you enter the sample
distribution scheme and sample volumes for the second bottle
group. If the remaining number of bottles or the capacity is not
satisfactory, reprogram the first section.
Pacing for the Second Bottle Group – T h e n e x t d i s p l a y,
Display #14, allows you to select time or flow pacing for the
second bottle group.
[TIME, FLOW]
SECOND BOTTLE GROUP
Depending on your selection, the STORM sequence will follow
one of the two paths shown for the second section in Figure 3-10
or 3-11.
Time-Pacing – When you select "TIME" from Display #14, two
time-pacing displays (#17 and #24) will follow.
____ MINUTE DELAY TO
SECOND GROUP SAMPLES
SAMPLE INTERVAL OF
____ MINUTE (1 - 9999)
Use Display #17 to set the delay to the second bottle group. Like
the delay to the first group sample, the delay to the second group
sample determines the period between the time the sampler is
enabled and the first sample is deposited in the second bottle
group. You can use this setting to fill the second bottle group
during the same time the sampler fills the first bottle group or
after the sampler fills the first bottle group. Figure 3-17 shows a
time diagram for a STORM routine that uses time pacing for
both the first and second bottle groups.
To fill the second bottle group after the first, be sure amount of
time you enter for the delay to second group is equal to (or
greater than, if necessary) the delay to the first group plus the
total amount of time required to fill the first group. The sampler
will begin timing both delays (delay to first and delay to second
bottle group) at the same time. Refer to the lower diagram in
Figure 3-17.
Entries made in Display #s 15, 23, and 24 (" -- MINUTE DELAY
TO FIRST GROUP SAMPLE," "TAKE -- TIMED EVENTS," and
"SAMPLE INTERVALS OF -- MINUTES") determine the
amount of time required to fill the first bottle group.
