<strong>6700</strong> SAMPLERS<br />
If you need to collect sampling results and partition data, do this<br />
before allowing the sampler to create and size the partitions. The<br />
stored data is lost as the sampler reformats its memory. As a<br />
precaution, the sampler displays the screen below.<br />
When YES is selected, the sampler clears the stored data and<br />
reformats the memory partitions. The sampler then displays the<br />
new capacity of the partition memory.<br />
If the duration is too short, try changing the data storage interval<br />
or eliminating unnecessary reading types in the Hardware or<br />
Module Setup. For example, a sampler configured with a 730 Bubbler<br />
Module and a rain gauge storing data at a one-minute interval,<br />
creates level and rainfall partitions that hold 13 days of<br />
readings. Changing the storage interval to two minutes extends<br />
the storage capacity to 26 days.<br />
The sampler does not have to be running a program to store<br />
readings. When the sampler is on, it stores readings at the<br />
selected data storage interval. Once the partition is filled, the<br />
readings roll over.<br />
When the sampler is running a program, the partitions become<br />
“triggered” by the programmed start time or the first enable<br />
time, whichever is later. A triggered partition continues to log<br />
readings at the selected interval, but will not replace any readings<br />
taken after the trigger event. The sampler fills the partition<br />
and then stops recording to preserve the data. The first reading<br />
preserved in a full partition is one hour before the trigger event.<br />
A full partition can be reset by starting another program or<br />
changing storage parameters.<br />
If you require continuous readings for analysis, be sure to collect<br />
the readings before the partition fills or rolls over to avoid gaps<br />
in the data.<br />
<strong>Isco</strong> offers a <strong>6700</strong> sampler controller with an expanded memory<br />
capacity. Instead of the standard 128 kilobytes, this controller has<br />
4 megabytes of RAM available for program and data storage. Contact<br />
the factory or your sales representative for more information.<br />
FLASH MEMORY AND SOFTWARE UPGRADES<br />
The sampler has Flash memory to store its software. With Flash<br />
technology, you can upgrade your sampler’s software without<br />
sending it back to the factory or replacing a chip. Simply connect<br />
a computer to the sampler and run the Flash Update program.<br />
