displays in this Directions For Use
booklet are in °F. International units
will display measurements in °C.
5. Insert the probe shaft into the
probe storage channel (Fig. 1).
1. Unpack the Welch Allyn Thermometer System. Check for any
damage that may have occurred
2. Select the desired probe (oral
probe - green body, rectal probe
- red body).
3. Insert the probe cord connector
into the probe receptacle. Check
that the connection is secure.
4. Observe the 7-second display
test, ensuring that no display segments are missing (Fig. 2).
6. Remove the tab from a box of 25
Welch Allyn disposable probe
covers and insert the box into the
holder on the thermometer.
1. Select the temperature measurement mode (normal or monitor - Fig. 3). Most temperatures
are taken in the normal mode.
2. Withdraw the probe from the storage channel and observe the display test. The unit will then display 84.0°F (28.9°C) with the low
temperature arrow ON until the
probe temperature rises above
3. Load a probe cover onto the
probe. Hold the probe collar with
thumb and forefinger, being careful not to hold or press the "eject"
button. Press the collar down
firmly to secure the cover (Fig. 4).
4. Take the temperature:
FOR ORAL TEMPERATURES,
insert the probe tip gently into the
patient's slightly opened mouth.
Carefully slide the probe under
the tongue on either side of the
mouth to reach the sublingual
FOR RECTAL TEMPERATURES, gently insert the probe
only 1 cm (3/8 of an inch) inside is
the rectal sphincter (less for infants and children). WARNING:
Incorrect insertion can cause
bowel perforation. (FIG. 5) Tilt
the probe to insure good tissue
contact and continue to keep buttocks separated until measurement cycle is complete.
5. During a temperature measurement cycle in the NORMAL mode,
a continuously increasing temperature should be observed on
the display. When the final temperature has been reached, a tone
will sound and a temperature will
be displayed. When using the
MONITOR mode, allow the temperature readout to stabilize for 3
minutes. The patient may then be
continuously monitored for as long
6. After the temperature measurement is complete, eject the probe
cover by firmly pressing the "eject"
button on the probe. (Fig. 1 ).
7. Insert the probe into the storage
channel to clear the display, in
preparation for another temperature. (Fig. 6).
1. Two Temperature Measurement Modes. Normal mode provides a rapid means of oral or
rectal temperature taking under
most conditions. Monitor mode

(28.9°C - 42.2°C).
• Battery Capacity: Up to 1000
hours normal use.
generally used for long term monitoring or when difficult situations
prevent accurate temperatures
from being taken in the normal
Two internal tests are activated each
time a temperature is taken:
1. Calibration Check: an internal
check for proper calibration.
2. Microprocessor Self Check: an
internal check for proper microprocessor operation, including a
test of the entire system.
• Calibration Accuracy: +/-0.2°F

CLEANING AND STERILIZATION
1. Error Indicators. One of four
indicators may appear on the display: Malfunction, Broken
Probe, Probe Position, and Low
Battery (Fig. 7).
Normal cleaning procedure is to wipe
with alcohol, warm water, or nonstaining disinfectant.
2. Battery Replacement. To
replace the batteries, remove the
battery compartment access
screw behind the probe cover
box (Fig. 8). Slide the access
cover to expose the batteries.
Replace with three new AA
Alkaline batteries. A 25 second
display test is automatically
performed following battery
• Calibration Key for verifying calibration - inserts in place of probe
plug and provides correct reading of 97.3°F (22.06°C).
• Oral and rectal probes
