Temperature Operation
Temperature Operation Mode Selection
Spot LXi with the SureTemp Plus thermometer takes a temperature in either Normal or 
Monitor Mode. The default setting is Normal Mode. 
In the Normal Mode, the SureTemp Plus thermometer “predicts” body temperature in 
the oral, axillary, or rectal modes. The thermometer takes an oral reading in approximately 
4 to 6 seconds, a pediatric axillary reading (ages 17 years and younger) in approximately 
10 to 13 seconds, an adult axillary reading (ages 18 years and older) in approximately 12 to 
15 seconds, and a rectal reading in approximately 10 to 13 seconds. Use the Monitor 
Mode when difficult situations prevent taking an accurate temperature in the Normal 
Mode. 
Normal Mode
Patient actions may interfere with accurate oral temperature readings. Ingesting hot or 
cold liquids, eating food, chewing gum or mints, brushing teeth, smoking, or performing 
strenuous activity may affect oral temperature readings for up to 20 minutes after activity 
has ended.
Probe contact with electrodes or bandages, poor tissue contact, taking an axillary 
temperature over clothing, or prolonged exposure of axilla to ambient air can cause 
inaccurate axillary temperature readings.
WARNING To ensure optimal accuracy, always confirm that the correct mode is 
selected.
WARNING Use only Welch Allyn probe covers. Using other manufacturers’ 
probe covers or no probe cover may produce temperature measurement errors 
and/or inaccuracy.
WARNING Always use a probe cover whenever coming into contact with a 
patient.
