11.1 Introduction to Grid and Sequential file formats
The
DFX-7
is equipped with two data file format options,
GRID LOG
and
SEQ LOG
.
The
GRID
file format is very similar to a spreadsheet format found in popular
software programs like Excel. A
GRID
is simply a table of readings. A location in a
grid is specified by giving a row and column coordinate. The rows are numbered
from 1 to 999 and the columns are labeled from A to ZZ (999 Rows & 52 Columns).
The sequential file format can be viewed as a file as a single column of up to 512
possible rows (readings), and a column of corresponding identifiers associated with
each individual reading. The identifier can be a combination of up to 10 numeric,
alpha, or special characters listed above, while the file name can consist of a
combination of up to 20 of the same character set. Note:
The identifier cannot start
or end with a special character.
Once a start and end ID are entered into the
DFX-7
and the log created, the
DFX-7
will automatically generate all the identifiers within
that range.
The following character set listed below are all the allowable characters that will be
used for both file formats:
GRID
&
SEQ LOG
. Any combination of these characters
can be used for creating a Name and Note regardless of the selected format. The
allowable characters are as follows:
Numeric characters:
0 – 9
Alpha Characters:
A – Z
Special Characters:
! ‘ _ # space / . – ( )
Multiple grids can be created and stored until the
DFX-7
’s memory is full. If the user
attempts to store a new file in the
DFX-7
and the size of the file exceeds the capacity
of memory, the
DFX-7
will respond with an error message indicating that the memory
is unable to store the new file.
The
DFX-7
can store a total of
8,000 readings
with a corresponding screenshot of
the
RF
or
RECT
views with every reading, as well as all the
DFX-7
settings for every
individual reading. If the graphics option is disabled, not saving screenshots, the
DFX-7
can store a total of
210,000+ readings
. The screenshot stored with the
reading will depend on what view the
DFX-7
was in at the time it was saved. For
example, if the view was in
RECT
, then a
RECT
will be saved with the reading.
In the sections that follow, the procedures for creating, using, and editing
GRID’s
and
SEQ LOG’s
have been combined together for the purpose of similarity in overall
functionality and structure. The illustrations below are snapshots of typical
GRID
and
SEQ LOG
file formats:
