6712FR Refrigerated Sampler

Section 5 Extended Programming

•Add or remove a refrigerator temperature sensor as I/O3

•Add or remove a SDI-12 sonde parameter with the Hardware Setup

•Reinitialize the sampler

The stored data is lost as the sampler reformats its memory. As a precaution, before clearing the memory, the sampler display will show the following message:

INTERVAL CHANGED --

DOWNLOAD DATA NOW

OR LOSE ALL DATA!

DONE

If you want to keep the stored data, download it before pro- ceeding. When DONE is selected, the sampler clears the stored data and reformats the memory partitions. The sampler then dis- plays the new capacity of the partition memory.

PARTITION MEMORY

WILL LAST 13 DAYS

If the duration is too short, try changing the data storage interval or eliminating unnecessary reading types in the Hardware or Module Setup. For example, a sampler configured with a 730 Bubbler Module and a rain gauge storing data at a one-minute interval, creates level and rainfall partitions that hold 100 days of readings. Changing the storage interval to two minutes extends the storage capacity to 201 days.

The sampler does not have to be running a program to store readings. When the sampler is on, it stores readings at the selected data storage interval. Once the partition is filled, the readings roll over.

When the sampler is running a program, the partitions become “triggered” by the programmed start time or the first enable time, whichever is later. A triggered partition continues to log readings at the selected interval, but will not replace any readings taken after the trigger event. The sampler fills the par- tition and then stops recording to preserve the data. The first reading preserved in a full partition is one hour before the trigger event. A full partition can be reset by starting another program or changing storage parameters.

If you need continuous readings for analysis, be sure to collect the readings before the partition fills or rolls over to avoid gaps in the data.
