The sampling program controls how often sample events occur
and what should take place at each event. A sample event may
happen when:
• you start a flow paced program that is programmed to
Sample at Start (Section 3.3.5).
• a time paced program reaches the First Sample time
and date,
• your programmed time interval has elapsed,
• your programmed number of flow pulses has been
reached, or
• a disabled sampler becomes enabled (Section 3.3.6).
At each event, the sampler:
1. Resets the programmed flow or time pacing interval.
2. Moves the distributor arm over the next bottle. (This step
does not occur for samplers configured with the 20 liter
composite bottle.)
3. Rinses the suction line (see Section 3.3.4).
4. Sends a three-second event mark signal that begins at
forward pumping. The sampler deposits the programmed
sample volume into the bottle.
If programmed to deposit a sample volume in more than
one bottle, the sampler:
a. Moves the distributor arm over the next bottle.
b. Deposits the programmed sample volume into the
bottle.
c. Repeats steps 4a and 4b until the programmed number
of bottles per event is reached.
5. Rinses the suction line (see Section 3.3.4).
There are four categories of sampling program instructions that
control the above actions in an event:
• Pacing instructions define what controls the sample
collection interval and its frequency.
• Distribution instructions define where the collected
liquid sample is placed.
