General Tools and Instruments DT4947SD - Manual (Page 7)

5. Enable or disable auto power off. Once the format of decimal point divisions has been
set and stored, the display will show the word “yES’ over the term “PoFF”. Press the Type
▲
or T1-T2 ▼ 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 power off function shuts off the DT4947SD after a period of
inactivity of ten minutes.
6. Enable or disable the beeper. Once the auto power off function has been enabled or
disabled, the display will show the word “yES” over the word “bEEP”. Press the Type ▲
or T1-T2 ▼ button until the desired setting (“yES” or “no”) is displayed, and then press
the REC/ENTER button to store the selection as the default.
7. Select the temperature unit. Once the beeper has been enabled or disabled, the lower
part of the display will show the term “t-CF”. Press the Type ▲ or T1-T2 ▼ 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.
8. Set the datalogging sampling time. Once the default temperature unit has been
selected, the display will show a value above the letters “SP-t”. Press the Type ▲ or
T1-T2 ▼ button to decrease or increase the value until the desired sampling time
appears above “SP-t”. The options are 0, 1, 2, 5, 10, 30, 60, 120, 300, 600, 1800 and
3600 seconds (0 seconds to 1 hour).
9. Format the SD card. Once the sampling time has been set and stored, the term “Sd-F”
will appear in the lower half of the display. Press the REC/ENTER button.
Pressing the REC/ENTER button causes the word “no” or “yES” to appear over the term
“Sd-F”. Press the Type ▲ or T1-T2 ▼ button to make a selection. Choose “yES” whenever
a new SD card is being used, or when a used card is being repurposed (from use with
another SD card instrument or a camera, for example) and all data on it is to be erased.
Choose “no” to preserve any data on a card previously used with this instrument.
If you choose “yES”, after you press the REC/ENTER button the instrument will prompt you
to confirm that decision by displaying the term “Ent” below “yES” and sounding three
beeps. To confirm that you want to begin the erasure/formatting procedure, press the
REC/ENTER button. “Ent” will then flash several times and the instrument will sound
another three beeps to confirm that the SD card has been erased and formatted.
Once the SD card has been set up, the display will then either return to the first of the
seven steps in the setup sequence—setting the current date and time—or show the term
“ESC”. If “ESC” appears, press the POWER/ESC button to exit the setup procedure and
enter normal operating mode.
