Measuring Temperature

Selecting the Temperature Scale

The Welch Allyn Spot Vital Signs can display temperature in either degrees Fahrenheit (°F) or
degrees Celsius (°C). To determine the current temperature scale, remove the temperature probe
from its holder and view the Temperature display, which shows either "°F" or "°C."
To change the temperature scale, you must enter the device's internal configuration mode:
1. Turn the Spot Vital Signs off.
2. Press both the Power and Blood Pressure Start/Stop buttons simultaneously. The device
enters its internal configuration mode.
3. Press the Mode button to cycle through the menu until you reach the temperature option
screen.
4. The first option illuminated on the temperature display is "°F ." Pressing the Next Patient/Clear
button once illuminates "°C."
5. When the desired temperature scale is selected, press the Mode button once to save this
change.
6. Turn the device off.
When the device is turned on, the new temperature scale is established as the default scale.
The device always reverts to this temperature scale.

Selecting Temperature Operation Mode

When configured with the temperature option, the Welch Allyn Spot Vital Signs takes a tempera-
ture in either Normal or Monitor mode.
In the Normal mode, the thermometer's microprocessor "predicts" body temperature in approx-
imately 4 seconds for oral temperatures, 10 seconds for axillary temperatures, and 15 seconds
for rectal temperatures.
For accurate oral temperatures, place the oral probe in the poste-
rior medial sublingual pocket.
Monitor mode is normally used when difficult situations prevent taking
an accurate temperature in the Normal mode. In Monitor mode, main-
tain probe contact with the tissue for at least 3 minutes for accurate
oral/rectal temperature measurement, and 5 minutes for accurate axil-
lary temperature measurement.
The default setting for the Spot Vital Signs thermometer is Normal
mode.
Note: Normal mode axillary temperatures are FDA approved for children under the age of four.
THE WELCH ALLYN SPOT VITAL SIGNS IS NOT INTENDED FOR USE ON NEONATAL PATIENTS.
