11.1 Introduction to Grid and Sequential file formats

The CMX

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 CMX

and the log created, the CMX

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 CMX

’s memory is full. If the user

attempts to store a new file in the CMX

and the size of the file exceeds the capacity

of memory, the CMX

will respond with an error message indicating that the memory

is unable to store the new file.

The CMX

can store a total of 16,000+ readings with a corresponding screenshot of

the DIGITS or B-SCAN views with every reading , as well as all the CMX

settings

for every individual reading . If the graphics option is disabled, not saving
screens hots, the CMX

can store a total of 210,000+ readings. The screenshot

stored with the reading will depend on what view the CMX

was in at the time it was

saved. For example, if the view was in B-SCAN, then a B-SCAN 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
