Flow Mode
Flow Modes differ from Time Modes in that instead of taking a sample after a time interval has elapsed, the
unit will take samples after receipt of a contact closure from an external device. Whether those contact
closures are based off Flow, pH, Level, ORP, DO, etc. is transparent to the sampler. The unit simply
acknowledges a contact closure was received and that in turn triggers the sample collection process. In
FLOW Mode the sampler does not control totalization, logging, or the meeting of certain parameters, etc. so
they must be done by the external device. Once the parameters have been met, a contact closure will be
output to the sampler. Every time a contact closure is received, the sample collection process is initiated.
The sampler will advance the spout, draw 1 sample and place it in a bottle. It will then wait for the next
contact closure while displaying a running tally indicating the number of samples taken to that point. This
will continue until the total number of bottles the unit is configured for (set in *99) each have a sample
placed in them or a bottle full condition occurs. If either of these two conditions occur, the sampler ends the
program.
Display on LCD
Explanation
SAMPLER READY
10:04
This display indicates the sampler is ready to program and displays
the current time. Press <FLOW> to begin programming.
PUSH START/OPTIONS
The program can then be started by pressing <START> or other
functions can be added. In this example, <START> was pressed.

The sampler is now waiting to accept contact closures to trigger the
sample collection process.
