5. Enable or disable auto power off. Once the format of decimal divisions has been set
and stored, the display will show the word "yES' over the term "PoFF". Press the SET
M 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 UV254SD after a period of inactivity of ten
minutes.
6. Enable or disable the beeper. Once the desired power management function has been
set and stored, the display will show the word "yES" over the word "bEEP". Press the
SET M button until the desired setting ("yES" or "no") is displayed, and then press the
REC/ENTER button to store the selection.
7. Select the thermocouple type. Once the beeper has been enabled or disabled, the
display will show the word "Set" over the word "type". Press the SET M button until
your optional thermocouple's type (K or J) appears on the right side of the display. Then
press the REC/ENTER button to store the selection.
8. Select the temperature unit. Once the thermocouple type has been set and stored, the
lower part of the display will show the term "t-CF". Press the SET M 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 M 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 M 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 formatted (or not), the display will either return to the first of the
eight 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.
