*03 Flow Mode - External Event
*03 is used for monitoring intermittent events by combining portions of Flow and Time modes. *03 differs
from regular flow modes based on the way the sampler interacts with the contact closures it receives. In
normal flow mode the sampler receives a momentary closure from an external device, and this initiates a
sampling cycle. In *03 the sampler also initiates a sample cycle based off the initial contact closure it receives.
Once it has received that initial closure, the contact must remain closed for *03 to operate as intended. By the
contact remaining closed, t he time portion o f the mode is brought into effect and the unit will t ake samples
based off a user set time interval. For example, assume the user has an external device with a relay that is
normally open. The user sets a high and low trip point within the device. If an event takes place based on the
high o r low set point, t he unit will send a closure t o the sampler. T his causes a sampling cycle t o t ake place.
If the contact does not remain closed, t he unit will act as if it were programmed fo r regular flow mode, and
simply take samples each time a contact closure is received. If the relay remains closed, however, the unit will
then start to count down the user set time interval and once that interval has elapsed, take a sample. Each time
the interval elapses, the unit will perform a sampling sequence. T his will continue until the total number o f
bottles the unit is configured for (set in *99) each have their set number of samples placed in them or a bottle
full condition occurs. I f the contact o pens before either of t hese t wo occurrences the sampler will suspend
operation until it once again receives a contact closure that remains closed. After receiving another contact
that remains closed t he sampler will begin where it left off from t he last contact closure.
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 03,
and press <ENTER>.
ENTER TIME INTERVAL
__ __:__ __ 04:30:02
Input a t ime interval in HH:MM format.
PUSH START/OPTIONS
04:30:02
If no add-on options are desired, press <START> to begin the
program. NOTE: DELAY START does not work with *03.
FLOW MODE (* 03)
__ __ __ __ 04:30:02
The sampler is now ready to receive contact closures and is
independently counting down the Time Override.
