Once a temperature sample has been taken and stored in the onboard RAM of the Viewer it can not be changed.  

The time and temperature display parameters can be changed if the user has the proper password, but the underlying data can not be altered.

When the collected data is downloaded to a computer the TView) program displays it as a chart.  The charts can be combined with other sensors or displayed separately.  They can also be printed out.  Additionally the charts can be exported to an XLS file which can be viewed with Excel.  If the data is saved rather then exported is is saved as an encrypted file with a TXV file extension, which can only be read or printed with the TView)program. If a previously saved 'txv' file is loaded into the TView) program a small icon appears on the screen indicating that you are viewing encrypted data.

If a 'xls' file is loaded into Excel, Word, Notepad or some other text editor type program it can be manipulated and re saved but can not be loaded into the TView) program. This meets the requirements of US regulation 21 CFR part 11 but the user is expected to take steps to ensure that the data files themselves are kept secure in accordance with the measures required under 21 CFR part 11.
