CHAPTER FOURTEEN
DATA STORAGE – SETUP, EDIT, & VIEW FILES
14.1 Introduction to Group (spreadsheet) format
Data is stored in the MiniMax in a spreadsheet like format called a GRID. A GRID is
simply a two dimensional table of readings. In the case of the MiniMax we'll refer to
a GRID as a GROUP. The location in a group is specified by giving a row and
column coordinate. The rows are numbered from 1 to 250 and the columns are
labeled from A to Z, then AA to ZZ giving a maximum of 51 possible columns.
The largest single grid that can be created in the MiniMax can contain 250 bolts, 1
unloaded length (L-REF), and 51 elongations. Multiple groups can be created and
stored until the MiniMax's memory is full. If the user attempts to store a grid in the
MiniMax when the memory is full, the MiniMax will respond with an error message
indicating that the memory is unable to store the new group.
The MiniMax can store a great deal of data, considering there is a 4 GB internal SD
card on the board. Each measurement stored can be considered a page of data, as
it stores the measurement, snapshot of the waveform, and all the settings of the
MiniMax at the time the measurement was recorded. The display views and
quantities can be toggled for each and every possible option of the MiniMax,
provided that the correct factors have been entered into the gauge and are being
used. To make this as clear as possible, the Display Views (RF, RECT, and DIGITS)
can be toggled with any stored measurement. Additionally, the Quantities (Time,
Elongation, Load, Stress, and %Strain) can be toggled with any stored measurement.
It's clear that the data recordation of MiniMax is an extremely powerful tool for
purposes of documentation.
14.2 Creating a new Group
Important Note: This entire section is a step by step guide to successfully create a
group. The instructions must be used in the sequential order specified, as follows:
In order to eliminate too much redundancy with multiple pass of the same exact steps
for each of the group list items, the following procedure will be listed once below.
