9.1.2 Calibration File Type
A calibration (CAL) file is designed specifically for storing calibration setups.
Calibration files have space to store one single ID with its corresponding waveform
and data. Separate calibration files are created for the different transducers, materials,
or test parts being used. The advantage to storing setup data in calibration files is that
the data can be quickly recalled to the live A-scan display (see “Recalling a File ID” on
page 113).
9.1.3 2-D Matrix Grid File Type
A two-dimensional (2-D) file sequence begins with the ID number that refers to the
first column and the first row. Then the column (or row) increments one value at a
time until the sequence reaches the last column (or row) value while the other
dimension stays constant. At this point, the other dimension increases from its first to
its next value. This continues until the ID number that refers to the last column and
last row is reached.
9.2 Data Logger Storage Capacity
The EPOCH 6LT data logger can store over 100000 IDs on 2 GB of available internal
memory.
9.3 Saving Data to Active Files
The EPOCH 6LT allows you to save data whenever there is an active file open with an
active ID. If there is no active ID and you try to save the data, the instrument displays
the error message “No active ID” at the top of the display.
There is no save button on the File menu because data is usually captured and saved
on the live A-scan screen.
To save data to an active file
