The Welch Allyn SureTemp Plus is a portable thermistor thermometer used for accurately
measuring body temperatures at oral, axillary, or rectal sites. The device measures
temperature by default in predictive (Normal) mode, during which it uses a predictive
algorithm to calculate patient temperature. If you cannot correctly measure the patient's
temperature in Normal Mode, the unit will automatically enter Monitor (Direct) Mode.
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.
