Flow Mode - Pulse Accumulation
FLOW Mode - Pulse Accumulation operates the same as FLOW Mode except instead of taking a sample after
every contact closure, a sample is taken after a set number of contact closures (from 2 - 9,999) have been
accumulated.
NOTE:
This program uses <DELAY START> for setting the number of contact closures to be
accumulated. The display will show the number of contact closures the sampler is programmed to accumulate
before taking a sample. Every time a contact closure is received, the sampler will decrease the number needed
on the display by one. This shows how many more contacts have yet to be accumulated before a sample is
taken. Once the set number of contact closures are received, the sampler will advance the spout, draw 1
sample and then place it in a bottle. It will then wait for the next accumulation. 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
04/30
04:30:02
This display indicates the sampler is ready to program and displays
the current time. Press <FLOW> to begin programming.
PUSH START/OPTIONS
04:30:02
To set the number of contacts to be accumulated in FLOW Mode -
Pulse Accumulation, press <DELAY START> and then the
<START> button.
DELAY IN PULSES?
__ __ __ __
04:30:02
The user is now prompted to set the number of contact closures the
sampler will accumulate before taking a sample (2 - 9,999). Until it
is changed or ends its cycle, it will always accumulate the same
number of pulses before taking a sample.
PUSH START/OPTIONS
04:30:02
Unless add-on options to the program are desired, press <START>.
FLOW MODE
__ __ __ __
04:30:02
This display shows the number of contact closures remaining before a
sample will be taken. As contact closures are received the sampler
counts down until it reaches 0. It will then take a sample and reset to
accumulate the entered number of contact closures again.
