Data Logger Manual Section 4: Front Panel Overview 4.1 Changing the display units The DLI-T comes with factory default display units of °C for both the internal temperature and external probe channels. These units can be easily changed by pressing the F3 button in the main screen and then selecting either F1 for the internal temperature or F2 for external probe.
Dwyer DLI-T Large: Both channels can be displayed and take up entire available screen space. Button pressing chain: Main Screen -> F4 -> F1 -> F4 -> F2 repeatedly to scroll or UP and DOWN to scroll 4.3 Checking the memory Status A status icon appears on all screens representing memory, but further information including percent memory left and number of readings taken can also be viewed. From the Main Screen press the F1 key to enter the Status screens then press F2 to view memory status information.
Data Logger Manual Section 5: DLI-T Function Reference 5.1 Main Screen The main screen of the DLI-T features a real-time display of most recently measured internal temperature and external probe data. At the bottom of the main screen are tabs corresponding to each of the four function keys. These tabs are used to access the four main function menus of the DLI-T: status, statistics, units, and setup.
Dwyer DLI-T 5.3 Statistics Menu Pressing the F2 key while in the Main Screen brings up the Statistics Menu. From the Statistics Menu, statistics generated from the conditions encountered by the device can be viewed in a variety of different styles including being sorted by channel and by type. The Statistics Menu also displays important statistics information as well as the option to clear the statistics at any time. 5.3.
