The data validation feature in ACR TrendReader standard software, available from JDL (Just Data Loggers, the official UK sole distributor for ACR), is used to inform the viewer that the printed or electronic data logger data file (TRW), an ACR TrendReader data file, that the data has or has not been modified since the data was 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)

Intrinsically safe temperature data logger
The JR-1001 intrinsically safe temperature recorder is an electronic recording device designed to measure and record changes in temperature at user set intervals in hazardous areas
Single-channel temperature logger is 16mm diam!
The jdl 'Little Logger' measures and records up to 2048 time stamped temperature recordings between -10C to +85C, and yet is contained in a small package of only 16mm diameter
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".
This Data Validation Feature is applicable to TrendReader standard software.
Current users of TrendReader can freely download the latest version of the software (v1.22) from the ACR website free.
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.
