   • Graph Display: Under the graph display submenu, you can view a real-time colour-coded temperature graph from each of the four channels. You can adjust the sample collection rate, as well as reset and record temperature information. The recorded data can easily be saved to the app and the device.
   • Data Download: Data download allows you to download previously logged data from your Center521. Once downloaded, you can save it to your device by pressing "Download". You can also choose to view the retrieved data in a graph or as a text list.
   • File Open: Within the "File Open" submenu, you can open, share and graph any of your previously saved data files.
