Data Management
XL2 File Validator
A check sum is written to the file at the end of every measure-
ment report. The XL2 Analyzer calculates the check sum auto-
matically based on the data content of the file. Using the XL2
File Validator PC-software, the contents of a data file may be
verified at any time. e.g. authorities can verify if the XL2 report
file is original or the data has been manually modified.
The software ”XL2 File Validator” is available for download for
all registered XL2 customers at https://my.nti-audio.com.
