- | === Format for Incoming Data - ASCII Text === | + | |
- | The output format for data generated by the analytical data system must adhere to a specific ASCII text format to enable MAX to be able to correctly interpret and store the data. Orsat has generated output formats for both the Totalchrom and EZChrom data systems. | + | |

- | * Instrument Name - (Format " | + | |
- | * Filename - specific format (see File Naming) | + | |
- | * Acquisition Time - the time the analytical data collection started. | + | |
- | * Process Date and time- the time the data file was generated | + | |
- | * Sample Name, generally Blank, Standard, Ambient Air, IQ-RTS, CS-LCS | + | |

- | - CAMS code (if available) | + | |
- | - Interval, units code and method codes required for AQS file generation | + | |
- | + | ||
- | ==== Site Permissions ==== | + | |
- | MAX allows for user-defined permissions for each user based on the users role. These roles define the activities available to that user. Users can be designated as Administrators, | + | |
- | === Roles === | + | |
- | * __Guest__ - viewing access only, no access to raw TX0 data, Screening tools, Generation of CSV output, AQS Files. | + | |
- | * __Operators__ - Same as Guest. Additional access to view TX0 data, generate CSV output and the ability to add or edit Certificates of Analysis, QA/QC table updates, and Site Information | + | |
- | * __Validators__ - Same as Operators with added ability to add or edit all features. | + | |
- | * __Admin__ - full access to all functions | + | |
- | + | ||
- | ==== Data Display ==== | + | |
- | MAX has many ways to review data. Various data views allow users to quickly evaluate current data for a given site as well as historical data. Daily tabular data as well as graphic display of specific targets over user defined times allows users to review ambient data to compare compounds or sites. | ||
- | === Monthly Site Information Page === | ||
- | The monthly site information page displays hourly data which has been collected. | ||
- | Site Info.png | ||
- | === QuickLooks === | ||
- | === Generate Charts === | + | |
+ | These rights are given to operators and do not include some features | ||
