handle will move slightly to engage the probe cover.
4. With the Rectal Mode indicator flashing, lift the patient’s tail with one hand. Using the
other hand, gently insert the probe only 1.5 cm (5/8 in.) inside the rectum (less for
small patients). The use of a lubricant is optional.
5. Tilt the probe so that the tip of the probe is in contact with tissue. Keep the hand
holding the patient’s tail in place, and hold the probe in place throughout the
measurement process. Rotating “walking” segments appear on the display,
indicating that measurement is in progress.
6. The unit will beep three times when the final temperature is reached. The
measurement site, temperature scale, and patient temperature will display on the
LCD. The final temperature will remain on the display for 30 seconds.
7. If you cannot correctly measure the patient’s temperature in
Normal Mode, the unit will automatically enter Monitor Mode. In
this mode, measurement time is extended. Either repeat the
temperature measurement in Normal Mode or keep the probe in
place for three minutes in Monitor Mode. The thermometer will not beep to indicate a
final temperature. Record the temperature before removing the probe from the site,
as the temperature reading is not maintained in memory.
WARNING 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.
WARNING Use only Welch Allyn probe covers. The use of other
manufacturer’s probe covers or no probe cover may produce temperature
measurement errors and/or inaccuracy.
WARNING Incorrect insertion of probe can cause bowel perforation.
