Tamper Evident Data Recording

[SteveD123]

AMS2750E covers pyrometric requirements for thermal processing equipment used for heat treatment. It covers temperature sensors, instrumentation, thermal processing equipment, system accuracy tests, and temperature uniformity surveys. 

Paragraph 3.2.7.1.1 of  AMS2750E states “The system must create electronic records that cannot be altered without detection”.

Anybody got any ideas how to do this with LabWindows?

Not so much of a LabWindows answer, but the first thing that comes to mind is separately storing a hash of your data set. However that arguably just doubles the number of places where you will need proper authentication, authorization and logging of user actions for access to the data. Alternatively, you could use a keyed hash stored with the data, assuming it was feasible to keep that key secret.
