CHAPTER FOURTEEN
DATA STORAGE – SETUP, EDIT, & VIEW FILES
14.1 Introduction to Group (spreadsheet) format
Data is stored in the
MAX II
in a spreadsheet like format called a
GRID
. A
GRID
is
simply a table of readings. In the case of the
MAX II
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 51 possible columns.
The largest single grid that can be created in the
MAX II
can contain
250
bolts,
1
unloaded length
(L-REF)
, and
51
elongations. Multiple groups can be created and
stored until the
MAX II
’s memory is full, which is a massive amount. If the user
attempts to store a grid in the
MAX II
when the memory is full, the
MAX II
will
respond with an error message indicating that the memory is unable to store the new
group.
The
MAX II
can store a great deal of data, considering there is a 4 GB internal SD
card on the board, as well as an external SD slot that will accept up to 64 GB cards.
It’s not likely a user will get close to using all the memory in this gauge. Each
measurement stored can be consider a page of data, as it stores the measurement,
snapshot of the waveform, and all the settings of the
MAX II
at the time the
measurement was stored. The display views and quantities can be toggled for each
and every possible option of the
MAX II
, 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
MAX II
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:
