13 MEASUREMENT - RECORDING YOUR READINGS
Your gauge is equipped with a data logger -. With a data file open, all your measurements are saved
into the file for later review and download to PC.
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 formatYou have a choice of two different file formats:
•
Grid format: Similar to a spreadsheet format in which each cell is used to store a reading. Cells
are referenced by the row number (1 to 999) and the column label (A to ZZ).
•
Sequential format: A single column of up to 512 possible rows (readings), and a column of
corresponding identifiers associated with each individual reading. The identifier can be a
combination of up to 10 alphanumeric/special characters (see below), however it must not
start or end with a special character. Once a start and end ID are entered into the gauge and
the log created, the gauge automatically generates all the identifiers within that range.
Data logger filename character setsAny 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 savedWhen a measurement is taken (irrespective of log file format),
the following information is saved:
•
The reading value.
•
A screenshot, the nature of which 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. This 'Save Graphics' option can be toggled on/off.
Memory capacityYou 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. Saved data must be deleted in order to make the
space available..
