4. Set the start and stop times for “loop data recording”—logging up to 12 channels of
temperature information during the same period (for example, 14:15 to 15:30) every day.
Once you have set the date and time, the display will show the flashing term “LooP” in
the second row of the left column. Press the REC/ENTER button and then—with “00”
flashing under the term "StAR" in the left column— use the TYPE ▲ and PAGE ▼
buttons to set the first of the four values that define the loop: the starting hour. Press the
REC/ENTER button to store your selection. Then use the TYPE ▲ and PAGE ▼ buttons
with “00” flashing below the term “t” in the right column to set the loop’s starting
minute. Again press the REC/ENTER button to store your selection. Repeat this sequence
twice more to set and store the loop’s ending hour and minutes values.
Once you have entered the fourth value—the loop’s ending minute—
the following screen will appear:
To enable recording of data during the specified loop duration, press either the TYPE ▲ or
PAGE ▼ button to change the “no” to a “yES” and then press the REC/ENTER button to
store the selection. To disable recording, press the REC/ENTER button without changing the
“no” to a “yES”.
5. Choose a decimal point or comma to represent the decimal division between integers
and fractions (for example, American-style 20.88 vs. European-style 20,88). Once you
have set the start and stop times of loop data recording and enabled or disabled the
function, the display will show the term “dEC” in the third row of the left column. Press
the REC/ENTER button. This will cause the term "dEC" to appear in the lower right
corner below the term “USA”. Use the TYPE ▲ or PAGE ▼ button to make “USA” or
“Euro” (as desired) appear above “dEC” and then press the REC/ENTER button to store
the selection as the default.
6. Enable or disable auto power off (APO). Once the format of decimal point divisions
has been set and stored, the display will show the term “PoFF” in the bottom row of the
left column. Press the REC/ENTER button and then press the TYPE ▲ or PAGE ▼
button until the desired automatic power off management scheme (“yES” for enable;
“no” for disable) is displayed. Press the REC/ENTER button to store the selection. If
enabled, the APO function shuts off the DT4208SD if no front-panel buttons are pressed
during any ten-minute period.
7. Enable or disable the beeper. Once the APO function has been enabled or disabled,
the display will show the term “bEEP” in the top row of the right column. Press the
REC/ENTER button and then press the TYPE ▲ or PAGE ▼ button until the desired
setting (“yES” or “no”) is displayed. Finally, press the REC/ENTER button to store the
selection as the default.
8. Select the temperature unit. Once the beeper has been enabled or disabled, the
display will show the term “t-CF”in the second row of the right column. Press the
REC/ENTER button and then press the TYPE ▲ or PAGE ▼ button until the unit you
prefer (“F” for Fahrenheit, “C” for Celsius”) is displayed. Then press the REC/ENTER
button to store the selection as the default.
