13.1 About the data logger
With a data file open, as you take measurements, the measurement data is stored in files in the
gauge memory.
Data logger file format: Measurements are stored in a file which has a grid format (similar to the
format of a spreadsheet) in which each cell of the grid is used to store a reading. Cells of the grid
are referenced by the row number and the column label. There are two file formats, GRID and
ENGINE:
•
A GRID file has a standard spreadsheet type format with row numbers from 1 to 999 and
column labels from A to ZZ.
•
An ENGINE file also has a standard spreadsheet type format, but with row numbers from 1 to
12 (clock positions) and column labels from A to L (cylinders). Typically, the clock position
measurements are scanned measurements over the entire length of the cylinder at that clock
position.
Data logger filename character sets: Any combination of the following characters can be used
for file names and sequential format identifiers:
•
Numeric characters: 0 - 9
•
Alpha Characters: A - Z
•
Special Characters: ! ' _ # space / . - ( )
What measurement data is saved: When a measurement is taken, the following information is
saved:
•
The reading value.
•
A screenshot of the measurement screen plus all the gauge settings. The screenshot stored
with the reading will depend on what view the gauge was in at the time the reading was taken.
For example, if the view was in B-SCAN, then a B-SCAN screenshot will be saved with the
reading.
Memory capacity: You can create and save as many data files as required up to the maximum
capacity of the gauge memory (32 Mbit). If you try to create a new file which exceeds the memory
capacity, the gauge will display an error message. In this instance, to free some space in memory,
you should consider deleting some of the existing files or transferring them to a computer. Your
gauge can store a total of 12 000 readings with a corresponding screenshot of every reading.
