Multi-Bottle Sampling Programs
*01 Flow Mode - Independently Timed Spout Advance
The *01 program is used to obtain flow proportional samples over a period of time. Each bottle the sampler is
configured fo r has a time interval (referred t o as a t ime window) during which it is active. S amples can only
be placed in THAT bottle during THAT active time window. O nce t he sampler is programmed, it waits for a
contact closure while counting down the time interval that was set. If it receives a contact closure, while
counting down t he Time Interval, a sample sequence will be initiated. T he sampler will advance t he spout,
draw 1 sample, and place it in the active bottle. For every contact closure received during the active time
window, the sampler will place 1 sample in the SAME active bottle. Once the first time window has elapsed
(all t he time windows have the same time increment), t he sampler will begin counting down the second time
window while waiting for contact closures for the next active bottle. This continues until all of the bottles (set
in *99) have at least 1 sample placed in them. A bottle could potentially have more than 1 sample if more
than 1 contact closure is received during the bottle’s active time window. If the sampler has not received a
contact closure by t he end o f t he active time window the unit will advance t he bottle spout and place 1 sample
in the bottle that had most recently been active.
N OTE: T here is no overflow protection in this mode. M ake sure t hat t he sample volume
is small enough compared t o t he flow rate t o prevent o ver-filling.
Display on LCD Explanation
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 01,
and press <ENTER>.
ACTIVE TIME INTERVAL
__ __: __ __ 04:30:02
The sampler then asks for an interval time. This is the amount of
time
(1 min to 99 hours and 59 min) during which t he sampler will place
samples in the active bottle. Enter the time in HH:MM format and
press <ENTER>.
PUSH START/OPTIONS
04:30:02
If no add-on options are desired, press <START> to begin the
program.
FLOW MODE (* 01)
__ __ __ __ 04:30:02
The sampler is now waiting to receive contact closures and is
independently counting down the interval time.
