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 thermocouple type

or

LOGGER 

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.

9. Set the datalogging sampling time

. Once the thermocouple type has been selected

and stored, the display will show a value above the letters “SP-t”. Press the SET 

or

LOGGER 

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).

10. 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 

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.
