Data Logger Manual Section 4: Front Panel Overview 4.1 Changing the display units The DLI-P comes with factory default display units of °C for temperature, %RH for humidity, and PSIA for pressure. These units can be easily changed by pressing the F3 button in the main screen and then selecting either F1 for temperature, F2 for humidity or F3 for pressure.
Dwyer DLI-P Large: Up to two channels can be displayed at a time with the option of using the UP and DOWN buttons to scroll to view the third. Button pressing chain: Main Screen -> F4 -> F1 -> F4 -> F2 repeatedly 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.
Data Logger Manual Section 5: DLI-P Function Reference 5.1 Main Screen The main screen of the DLI-P features a real-time display of most recently measured temperature, humidity, and pressure 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-P: status, statistics, units, and setup.
Dwyer DLI-P 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.
