Data Logger Manual Section 3: Important Status Icons 3.1 Battery Status Full Battery Empty Battery Battery status icons indicate the state of charge of the batteries. When the battery empty indicator is displayed, the battery should be replaced. 3.2 Memory Status Memory Empty Memory Full The memory status icons indicate the amount of memory left for data storage. If the DLI2 is in wraparound mode, the memory status icon will always indicate empty. 3.
Dwyer DLI2 3.4 Delay Start Indicator The delay start icon indicates that a logging operation is scheduled for the future. 3.5 Wait Icon The wait icon indicates that the device is busy. 3.6 Stop Icon Indicates that the DLI2 is not currently taking readings. 3.7 External Power Icon Indicates that the DLI2 is powered by an external source. 3.8 Reset Icon Indicates that the device has been reset.
Data Logger Manual Section 4: Front Panel Overview 4.1 Changing the display units The DLI2 comes with factory default display units of PSI for pressure and the real-time pressure graphing feature. These units can be easily changed by pressing the F3 button in the main screen and then selecting F1 for pressure or F2 for the pressure graph. After selecting the channel, the available units can be scrolled through by either pressing the channel’s function key repeatedly or using the UP and DOWN keys.
Dwyer DLI2 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. Button pressing chain: Main Screen -> F1 -> F2 4.
Data Logger Manual Section 5: DLI2 Function Reference 5.1 Main Screen The main screen of the DLI2 features a real-time display of most recently measured pressure data and a real-time graph of the 100 most recently recorded data points. 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 DLI2: status, statistics, units, and setup.
Dwyer DLI2 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.
Data Logger Manual 5.4 Units Pressing the F3 key while viewing the Main Screen will access the Units Selection screen. Here the measurement units can be easily changed. In the Units Selection screen the F1 function key corresponds to the pressure channel and the F2 key corresponds to the pressure graph.
Dwyer DLI2 Note: Use of the DLI2’s graphing function will reduce the battery life of the device, particularly when not logging. To increase battery life either deactivate the graphing function by turning it to “Hide” in the Adjust Visibility screen, increase “auto time” in the Display Update Mode screen, or change the Graph Source from ‘auto’ to ‘reading’. Alternatively, use the AC adapter for continuous power and graphing ability. 5.5.i.
Data Logger Manual Display The DLI2’s LCD has options to be either on continuously or turn off automatically after five minutes of inactivity. This option can be changed by first pressing the F1 key to highlight the display parameter configuration tab. Once the tab is highlighted the option can be changed by pressing the F1 key repeatedly or using the UP and DOWN keys to select either “On” or “Auto”. Backlight Like the display, the LCD backlight also has power saving options.
Dwyer DLI2 5.5.ii.c Power Status Selecting “MORE” by either pressing the F4 key or the OK key while viewing the Display Update Mode screen brings up the Power Status screen. On this screen the battery type is displayed and should be changed by the user based on whether a Lithium or Alkaline battery is used in the DLI2. This can be changed by first pressing the F1 button to highlight the type parameter configuration tab.
Data Logger Manual 5.5.iii.d Device Version Pressing the F4 key while viewing the Maximum or Minimum Device Range screens will display the Device Version screen, containing information such as firmware revision number and communications baud rate. Values on this screen cannot be modified. 5.5.iii.e Firmware Version Firmware details can be viewed by pressing the F2 key while viewing the Device Version screens.
