<strong>6100CR</strong> <strong>Refrigerated</strong> <strong>Sampler</strong><br />
Section 2 Programming<br />
at one o’clock, it will skip the one o’clock sample and reset<br />
the timer with one hour and take the next sample at two<br />
(if the sampler is then enabled). The sample event will be<br />
logged as an error.<br />
• Selecting DELAY means that if the sampler enable is set<br />
to delay and is disabled when the time for taking a<br />
sample occurs, it will delay the collection of the sample<br />
until the sampler becomes enabled. At that time it will<br />
reset the counter so that the succeeding sample will be<br />
one sampler interval after the time the delayed sample<br />
was actually collected.<br />
2.4 The PROGRAM<br />
Sequence<br />
Note<br />
You must have a flow meter connected to the <strong>6100CR</strong> if you<br />
want to use flow pacing. The flow meter supplies the flow<br />
pulses, signals to the sampler that indicate volumes of flow.<br />
1. To begin the Program sequence, Press the Program key.<br />
Sample pacing refers to the way the sampler determines<br />
the interval between samples.<br />
SAMPLE PACING<br />
TIME FLOW<br />
· Selecting TIME means you will take a sample after a<br />
specific period of time has passed.<br />
· Selecting FLOW means you will take a sample only<br />
after a specific flow volume has passed. If the flow is<br />
variable, the time interval may vary considerably<br />
between samples.<br />
2. If you select TIME, the sampler will ask you to enter an<br />
interval of time. The smallest amount of time that can be<br />
entered is 15 minutes. The following screen will appear:<br />
SAMPLE EVERY<br />
XX HOURS XX MINUTES<br />
While it is possible to program a sample interval of 15 minutes,<br />
other program settings may prevent the sampler<br />
from completing the sample even within the 15 minute<br />
interval. For example, you could program a strainer purge<br />
cycle of 600 seconds, (ten minutes). Added to the one<br />
minute pre-cooler purge and the one to two minute bottle-fill<br />
time, the long purge could easily exceed the time<br />
available if more than one bottle per event is required by<br />
the program. In such a case, the sampler, once started, will<br />
sample continuously. Also, the performance of the sample<br />
