The data validation feature in ACR TrendReader Standard software is used to inform the viewer whether data have or have not been modified since they were extracted from the data logger.
The data validation feature in ACR TrendReader Standard software, available from JDL, is used to inform the viewer whether data have or have not been modified since they were extracted from the data logger.
Data files are also assigned rights, read-only (the viewer can only view, not modify the processed data file) or CRC validation only (the file can be modified but will fail validation).
If a file is modified, even with the correct name and password, the file will fail validation.
This is to ensure that the data in the logger is the same data that is being viewed.
Since the data logger itself is tamper-proof (no buttons or switches), the entire system is protected from data manipulation.
The Food and Drug Administration (FDA) allows the use of electronic records with electronic signatures.
The FDA regulation, 21 CFR Part 11, outlines the requirements of the "system" used to gather and maintain electronic records and signatures.
The key to the regulation is that data must be secure (also known as validatable).
The term used to describe the process for ensuring integrity of data is "data validation".
The data validation feature is applicable to TrendReader Standard software.
Current users of TrendReader can freely download the latest version of the software (v.
1.22) from the ACR website (www.acrsystems.com).
All ACR data loggers using TrendReader Standard software (SmartReader series, SmartReader Plus series and Owl series.) can use data validation.
Validation is used in many industries such as, pharmaceuticals, food and drinks production, food preparation and transportation, hospitals, and many other critical applications.
