Tips for Taking Pediatric Axillary Temperatures 
with SureTemp®Plus
1. Avoid contact with electrodes, wires, tape, clothing, etc.
2. Ensure the probe tip is completely surrounded by tissue 
at all times. Prolonged exposure of the axilla to ambient air can 
cause inaccurate readings.
3. Use of Welch Allyn disposable probe covers is recommended. 
Use of any other probe cover may result in inaccurate 
temperature readings.
4. If you question a reading, recheck the temperature using 
the Monitor Mode on your thermometer. Take an axillary 
temperature as described.
> Continue to hold the probe in place after the temperature displays
>
Press the Mode Selection button until the Monitor Mode 
indicator appears on the screen
> Continue taking the temperature for approximately five minutes
> Long-term continuous monitoring is not recommended in any mode
