The *12 mode functions almost identically to *10 mode, however, in this mode, up to 24 separate bottle
groups can be created which accept composite samples. *12 is useful when it is not possible to collect
samples on a regular basis, such as on a weekend or at a remote site. In this mode the user selects the number
of bottle groups, how long each group is active (receives samples), the maximum number of samples a group
will take, and a t ime override. NOTE: T he number of bottle groups is entered, not the number of bottles in a
group. A fter pushing <START>, t he sampler immediately begins counting down the Delay Start. O nce the
Delay Start has finished counting down t he sampler will be ready t o r eceive an event (contact closure or time
override). T he finish of t he Delay Start will also start t he t ime override counting down. I f t he sampler
receives an event, the unit will initiate t he sampling sequence. T here are several simultaneous actions.
1) The spout will advance t o the first bottle in t he active bottle group and begin the sampling process.
2) The active bottle group time will begin counting down. NOTE: M ake sure t he active time period allows
enough time to collect all t he samples required. If the active time period elapses before the Samples per Bottle
has been satisfied, the unit will finish t he sequence in progress and t hen mo ve to the next bottle group without
completing the current bottle group.
3) The t ime o verride will reset and begin counting down again. The override time causes the unit t o take
samples if a contact closure fails to occur. T he override t ime starts counting down immediately after pressing
<START>. NOTE: The override time must be longer than the time it takes for the sampling sequence to
complete. I f it is not, the override time will elapse while the unit is in a sampling sequence causing another
sequence t o begin immediately after finishing t he previous o ne.
The first bottle group will be active and receive all samples for its active time period, up to the maximum
number of samples. If the maximum is reached, the sampler will still wait out t he rest of the active time before
switching to the next bottle group. After the initiation of a sampling sequence, t he sampler will advance t o the
first bottle in t he group. T he unit will place 1 sample in this bottle, and then advance to the next bottle in the
group and deposit a sample. T his will continue until all t he bottles in t he group have 1 sample placed in them
(see NOTE on #2 above). T he sampler will then wait fo r another event (contact closure o r a time override
elapse (see NOTE on #3 above)). W hen t he event o ccurs the unit will place another sample in each bottle of
the active group. T his will continue, as events take place, until the specified number of Samples per Bottle is
reached and all Bottle Groups have been utilized. See page 2-39 for a full explanation of how bottle groups
are divided and what o rder the spout fills the bottles.

SAMPLER READY
04/30 04:30:02
This display indicates the sampler is ready t o program and displays
the current time. Press the * key t o begin programming.
ENTER * MODE
__ __ 04:30:02
The sampler is now prompting fo r a star mode to be input. E nter the
numbers which represent the star mode of choice, in this example 12,
and press <ENTER>.
SAMPLES PER BOTTLE?
__ __ 04:30:02
Enter number of samples per bottle as a 2-digit number (1-99).
Make sure the volume to be placed in the bottles is not greater than
the actual volume of the bottles.
