DATA STORAGE – SETUP, EDIT, & VIEW FILES
10.1 Introduction to the Grid file format
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 specific
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 following character set below are the characters that can be used when when
creating a name or note as follows:
Numeric characters: 0 – 9 Alpha Characters: A – Z
Special Characters: ! ' _ # space / . – ( )
Note: The name and note fields are 20 charters in length using any combination of
the above character set.
Multiple grids can be created and stored until the MMX-7's memory is full. If the user
attempts to store a new file in the MMX-7 and the size of the file exceeds the capacity
of memory, the MMX-7 will respond with an error message indicating that the
memory is unable to store the new file.
The MMX-7 has a 4gb SD memory card for virtually unlimited storage capacity.
Along with every measurement stored, is a corresponding screenshot of the DIGITS,
RF, RECT, or B-SCAN views, as well as all the MMX-7 settings for every individual
measurement. The screenshot stored with the reading will depend on what view the
MMX-7 was in at the time it was saved. For example, if the view was in RECT, then
a RECT waveform will be saved with the reading.
The sections that follow are a guide for creating a grid:
