Appendix B: Data File Types

EPOCH 650 ultrasonic flaw detectors enable you to create several file types based on
application requirements. There are two standard file types, calibration and
incremental, and advanced file types for corrosion-style data logging.
B.1 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 screen using the Quick Recall parameter.
B.2 Incremental file type
Incremental (INC) files are designed for general inspection data storage, and can
contain more than one ID for storing file data. Each time the file is saved, the ID
increments using the following incrementing rules:
• Only the portion of an ID number that consists of digits and letters (no
punctuation marks), beginning with the right-most character and extending
leftward to the first punctuation mark or to the left-most character (whichever
comes first), can increment.
• Digits are cycled 0, 1, 2,..., 9, 0, and so on. The 9 to 0 transition is done only after
incrementing the character to the left. Letters are cycled A, B, C,..., Z, A, and so on.
The Z to A transition is done only after incrementing the character to the left. In
either case, if there is no character to the left or if the character to the left is a
punctuation mark, then the ID number cannot increment.
