The touch screen of an ETC combustion control system maintains a backup of the most recent commissioning data set. This can be displayed as a QR code by the system. This app allows the QR code to be scanned by an Android phone or tablet and the backup file (CBU) to be retrieved. The CBU file is stored in the phone and can be viewed and emailed from within the app. Optionally, a spreadsheet can be created in the users Google account using 'Google Sheets'.
