SETUP

1. Choose the power source

. Before using the DTH3007SD, make sure it is powered by

fresh batteries or an optional 9VDC AC adapter plugged into the bottom jack on its right
side (callout 1-12).

To remove the battery compartment cover (callout 1-13), remove the two screws holding it
in place (callout 1-14). Then install six “AA” batteries in the correct orientation, using the
polarity marks on the inside of the compartment as a guide. Replace the cover by replacing
the two screws.

2. Install an SD card

. To prepare for setup, also install the supplied 2 GB SD memory card

or another card with a capacity from 1 GB to 16 GB in the socket on the bottom of the
instrument (callout 1-9). When installing the card, make sure its gold contacts are facing
front and push the card into the socket until you hear a click. To remove the card, push it
in until you hear a click and the card pops out.

Now power on the instrument by pressing the POWER/ESC button (callout 1-2) to generate
a short beep. (To power off the DTH3007SD, press the POWER/ESC button and hold it until
the instrument responds with a long beep.)

When the meter powers on, a series of transient startup screens will briefly appear. Once
the display has stabilized, perform the following eight setup steps in the order presented.

3. Set the date and time

. Press the SET 

button (callout 1-5) and hold it for at least five

seconds, until the word “dAtE” appears in the center of the display, along with the
flashing value “00.00.00” at the lower left, above “yy.mm.dd”. 

Set the current year by pressing the SET 

or LOGGER 

button repeatedly until the

correct value appears above “yy”. Quickly (within three seconds), press the REC/ENTER
button to store the setting. The next screen that appears will have the value above “mm”
flashing. Use the SET 

or LOGGER 

button to navigate to the current month and press

the REC/ENTER button to store the setting. When the next screen flashes the value above
“dd”, again use the SET 

or LOGGER 

button to navigate to the current day and press

the REC/ENTER button to store the setting.
