14.1 Introduction to Group (spreadsheet) format
Data is stored in the MINI-MAX in a spreadsheet like format called a GRID. A
GRID is simply a table of readings. In the case of the MINI-MAX they will be
discussed in terms of a GROUP. The location in a group is specified by giving a
row and column coordinate. The rows are numbered from 1 to 99 and the
columns are labeled from A to Z, then AA to ZZ giving a maximum of 52 possible
columns.
The largest grid that can be held in the MINI-MAX can contain 250 bolts, 1
Unloaded length (L-REF), and 51 Elongations. Multiple groups can be created
and stored until the MINI-MAX’s memory is full. If the user attempts to store a
grid in the MINI-MAX when the memory is full, the MINI-MAX will respond with
an error message indicating that the memory is unable to store the new group.
The MVX can store a total of 8,000 readings with a corresponding waveform
stored with every reading. The Display Views and Quantities can be toggled
for each and every possible option of the MINI-MAX, 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. Also, the Quantities (Time, Elong, Load,
Stress, and %Strain) can be toggle with any stored measurement. Therefore,
the data recordation of MINI-MAX 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
