5.3.3 LOGGING TO 650 MEMORY WITH A SITE LIST
In the example above, you learned how to log data to 650 memory that had file and site designations input
to the logger at the time that the data was logged in the field. It is also possible, and in most cases more
convenient, to place file and site designations into the 650 memory in the office or laboratory before
moving to the field for logging studies. This is particularly true if you are aware of the sites at which you
will be determining water quality data and/or which you will be visiting on a regular basis. The following
section describes how to set up site lists which contain entries designated “Site Designations” that will be
instantly available to the user in the field to facilitate the logging of data in the field with pre-established
naming of files and sites. There are two kinds of Site Designations available for use in Site lists:
•
Site Designations associated with applications where data from a single site is always logged to a
single file. This type is referred to as a “Single-Site Designation” and is characterized by two
parameters – a file name and a site name. Files logged to 650 memory under Single-Site Designations
will be characterized primarily by the File name, but will also have the Site name attached, so that it is
viewable in either the 650 File directory or in EcoWatch for Windows after upload to a PC
•
Site Designations associated with applications where data from multiple sites are logged to a single
file. This type is referred to as a “Multi-site Designation” and is characterized by three parameters – a
file name, a site name, and a site number. Files logged to 650 memory under Multi-site Designations
are characterized by a file name, but not a site name, since multiple sites are involved. However, each
data point has a Site Number attached to it so that the user can easily determine the sampling site when
viewing the data from the 650 File menu or processing the data in EcoWatch for Windows after upload
to a PC.
When reading the following section on the use of the 650 Site list, remember that a Site List is a
compilation of individual entries called Site Designations. Single-Site Designations are used when the
data from a particular location is always logged to the same single file. A Single-Site Designation is
characterized by a unique file name. Multi-Site Designations are used when data from several locations
are logged to a single file. For Multi-site Designations, there will a single File Name with multiple Site
Names and Site Numbers. The following displays show examples of Single and Multi-Site Designations.
