General Tools and Instruments DT4208SD - Manual (Page 6)

SETUP INSTRUCTIONS
1. Choose the power source. Before using the DT4208SD, make sure it is powered by
fresh batteries or an optional 9VDC AC adapter plugged into the DC9V jack on its right
side (callout 1-13).
To remove the battery compartment cover (callout 1-16), remove the two screws (callout
1-17) holding it in place. Then install eight “AA” batteries in the correct orientation, using
the polarity marks on the inside of the compartment as a guide. Replace the cover and
secure it by tightening the two screws.
2. Install an SD card. To prepare for setup, also install the supplied 2 GB SD card or
another card of 1 GB to 16 GB capacity in the socket on the right side of the instrument
(callout 1-10). When installing the card, make sure its gold contacts are facing the back
of the instrument 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 DT4208SD, press the POWER/ESC button and hold it until
the instrument responds with a long beep.)
When the temperature recorder 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 1-8) and hold it for at least five
seconds, until the word “dAtE” appears flashing on the top line of the left column of the
display.
Quickly (within three seconds), press the REC/ENTER button. Set the current year by
pressing the TYPE ▲ or PAGE ▼ button repeatedly until the correct value appears flashing
on the top line of the left column. Quickly (within three seconds), press the REC/ENTER
button to store the setting. The next screen that appears will show the value “01” flashing
on the second line. Use the TYPE ▲ or PAGE ▼ button to navigate to the current month
and press the REC/ENTER button to store the setting. When the value “01” begins flashing
on the third line, again use the TYPE ▲ or PAGE ▼ button to navigate to the current day
and press the REC/ENTER button to store the setting.
(If you press buttons too slowly in setup mode, the screen will revert to the normal, real-
time measurement display. To return to the first step in the setup sequence, press and hold
the SET button again. To move ahead to the next field in the sequence or to the next
parameter, press the HOLD/NEXT button.)
Once you have set the date, the display will prompt you to set the hour, minute and second
of the current time, in 24-hour format. The three values appear on the top three lines in the
right column of the Date/Time Setting screen. To set each value, again use the TYPE ▲ or
PAGE ▼ buttons to navigate to the correct values, followed by the REC/ENTER button to
store the setting.
