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. After selecting a 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(temp), F2(probe) -> function key repeatedly or UP and DOWN

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

By default the DLI-T displays recently measured values of both channels (internal temperature and external probe) on its Main Screen with the two channels taking up the maximum amount of screen space available. Channels 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 corresponds to the internal temperature channel and F2 to the external probe. Pressing these function keys 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. Any number of channels between zero and two may be shown.

Button pressing chain:

Main Screen -> F4 -> F1 -> F1(internal temp) or F2(external probe)

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: Both channels can be displayed and appear much smaller than the available screen space.

Medium: Both channels can be displayed and take up two-thirds of available screen space.

Page 9

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.

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 DLI-T’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 repeatedly in any screen.

Button pressing chain:

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

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. 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 7) 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 lack of memory or preprogramming in the Dwyer software. The rate at which the DLI-T 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 DLI-T’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

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