Safety and Warnings
WARNING No modification of this equipment allowed.
WARNING Patient injury risk. Prior to taking a temperature, instruct the patient
not to bite down on the probe as patient injury and damage to the probe may
result.
WARNING Patient injury risk. Use only Welch Allyn single-use disposable probe
covers. A new probe cover needs to be used with each new temperature
taken. Never take a temperature measurement without a single-use probe cover
securely attached. Failure to use a probe cover can cause patient discomfort from
a heated probe, patient cross-contamination, and inaccurate temperature
readings.
WARNING Patient injury risk. Inaccurate measurement risk. Oral/axillary probes
(blue ejection button at top of probe) and blue removable probe wells are used for
taking oral and axillary temperatures only. Rectal probes (red ejection button) and
red removable probe wells are used for taking rectal temperatures only. Use of
the incorrect removable probe well could result in patient cross-contamination.
Use of the probe at the wrong site will result in temperature errors.
WARNING Patient injury risk. When taking rectal temperatures, insert the probe
tip only 5/8 inch (approximately 1.5 cm) inside the rectum of adults and only 3//8
inch (approximately 1 cm) inside the rectum of children to avoid the risk of bowel
perforation.
WARNING Inaccurate measurement risk. Never take an axillary temperature
through the patient’s clothing. Carefully place the probe in the axilla, avoiding
contact with other objects or material.
WARNING Patient injury risk. Continuous measurement durations of 3 minutes
at the oral and rectal sites and 5 minutes at the axillary site are recommended for
accurate measurement. Do not continuously measure beyond 10 minutes in any
mode.
WARNING To ensure patient safety and temperature measurement accuracy,
use only accessories and supplies recommended or supplied by Welch Allyn.
WARNING Never use a damaged temperature probe. The thermometer consists
of high-quality precision parts and should be protected from severe impact or

Introduction
Please follow the operating and maintenance instructions provided in this manual to
ensure years of accurate and reliable service. Please read these instructions thoroughly
before using the instrument, and then store these instructions in a safe place for future
reference.
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.
