Welch Allyn Medical Diagnostic Equipment Thermometer 690 User Manual

•

Use single-use Welch Allyn disposable probe covers to limit patient cross-contamination. 
The use of any other probe cover may produce temperature measurement errors or result 
in inaccurate readings. 

•

Do not take a patient’s temperature without using a Welch Allyn disposable probe cover. 
Doing so can cause patient discomfort, patient cross contamination, and erroneous 
temperature readings.

•

Long-term continuous monitoring beyond three to five minutes is not recommended in any 
mode. 

•

Biting the probe tip while taking a temperature may result in damage to the probe.

•

Oral/axillary probes (blue ejection button at top of probe) and blue oral/axillary removable 
probe wells are used for taking oral and axillary temperatures only. Rectal probes (red 
ejection button) and red rectal removable probe wells are used for taking rectal 
temperatures only. Use of the probe at the wrong site will result in temperature errors. Use 
of the incorrect removable probe well could result in patient cross contamination.

•

To ensure patient safety and temperature measurement accuracy, use only accessories 
and supplies recommended or supplied by Welch Allyn.

•

Equipment is not suitable for use in the presence of a flammable anesthetic mixture with 
air or with oxygen or nitrous oxide.

•

The thermometer case, connectors, and probe are not waterproof. Do not immerse or drip 
fluids on these items. Should this occur, dry the device with warm air. Check all operating 
functions for proper operation.

•

Do not take an axillary temperature through patient’s clothing. Direct probe cover to skin 
contact is required.
