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.

Button pressing chain:

Main Screen -> F3 -> F1(pressure) or F2 (pressure graph) -> function key repeatedly or UP and DOWN

4.2 Changing the number, type, and size of channels viewed

By default the DLI2 displays recently measured values of the pressure channel and the real-time pressure graph on its Main Screen in a large size font. The channel and graph can, however, be hidden or viewed on a smaller or larger scale.

To change the number and type of displayed channels:

From the Main Screen, press the F4 key to enter the Setup Menu and from this menu press the F1 key to enter the Display screen. On this screen, F1 and F2 correspond to the Pressure channel and Pressure graph respectively. Pressing these function keys repeatedly will cause the channels to scroll between “show” or “hide” channels displaying “show” will appear on the main screen and channels displaying “hide” will not.

Button pressing chain:

Main Screen -> F4 -> F1 -> F1(pressure) or F2 (pressure graph)

To change the size of displayed channels:

From the Main Screen, press the F4 key to enter the Setup Menu and from this menu press the F1 key to enter the Display screen, then F4 to scroll to the next screen. Here the F2 key will change the size of the channels viewed. By pressing F2 repeatedly the size parameter will scroll between 3 sizes: small, medium, and large.

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. 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

4.4 Checking power status

A battery status and external power status (if available) icon appear on all screens, but percent battery power remaining and external power presence as well as battery type, current battery voltage, and current external voltage can also be viewed. From the Main Screen press F4 to view the Device Conﬁ guration Menu, F2 to access the power options, then F4 twice to view the Power Status screen, including battery power percent remaining and the presence of external power. Battery type and battery voltage are also displayed, as well as external power voltage (if connected).

Button pressing chain:

Main Screen -> F4 -> F2 -> F4 -> F4

4.5 Changing the contrast

The DLI2’s LCD screen contrast values can be changed in two ways. One method is outlined in the Function Reference Guide. A faster, simpler way involves simultaneously pressing the CANCEL and UP or DOWN button repeatedly in any screen.

Button pressing chain:

CANCEL + UP repeatedly (to increase) or DOWN repeatedly (to decrease)

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. The left side of the main screen and all subsequent screens of the device is where important status information icons can be found (detailed in Section 3: Important Status Icons – page 5) including recording status, memory status, busy status, external power status, and battery power status.

5.2 Status Menu

Pressing F1 on the main screen brings up the Status menu. The ﬁ rst screen that appears in the Status Menu is Run Parameters, but the Memory Status and Time screens can also be viewed by pressing the F2 and F3 keys respectively.

5.2.i Run Parameters

The Run Parameters screen displays important information regarding the device’s current recording session. These parameters include the time and date the recording session started (start time and start date), the time and date the recording session will end (stop date and stop time) due to either a full memory or preprogramming in the Dwyer software. The rate at which the DLI2 is recording (rate) is also displayed. The device’s current status (either running or stopped) is the last parameter on the Run Parameters screen.

5.2.ii Memory Status

The Memory Status screen is where all information regarding the DLI2’s memory. This screen displays the percent of memory space currently available (memory left), the number of readings currently stored on the device (readings), the maximum number of readings the device can record (max readings), as well as information about the wrap feature displaying either “disabled” or the number of wrap readings currently stored in memory.

5.2.iii Time and Date

The time and date screen displays current time data including the current time and date, time and date of last measured data, and current time zone.
