Thermometer. Please follow the operating and maintenance instructions provided

The Welch Allyn SureTemp Plus is a portable thermistor thermometer used for
accurately measuring body temperatures at oral, axillary, or rectal sites.
Normal body temperature is a range, which varies from person to person and is
influenced by factors such as time of day and an individual’s level of activity,
ingested medications, age, and gender. A person’s normal temperature tends to
decrease with age.
The following table shows that ranges of normal also vary by site. Do not directly
compare measurements from different sites.
This booklet provides informative tips and instructions for using the SureTemp
Plus model 690 and model 692 thermometers. The chart on the following page
provides details about the differences between these SureTemp Plus
instruments.
