Exergen temperature: Troubleshooting

Unable to get an 
accurate 
measurement. 

The patient is agitated or combative.

Consider using the alternate sites: femoral artery or 
lateral thoracic.

Possible false 
reading.

The patient's forehead is in a direct 
draft from a vent or fan.

Remove the source of the draft. Each 10° difference in 
ambient temperature can cause a 1° error in the 
reading.

The thermometer is in a different 
ambient temperature than patient 
(e.g., window ledge directly exposed 
to hot sun or cold weather, or in 
direct line of air conditioning or fan).

Store the scanner at the same ambient temperature 
as the patient for at least 20 minutes before taking a 
temperature measurement. Each 10° difference in 
ambient temperature can cause a 1° error in the 
reading.

Scanner readings 
are not 
comparable to 
current/traditional 
methods.

Arterial temperature is close to rectal 
temperature, approximately 0.4° C 
(0.8º F) higher than oral temps. 

Expect larger differences at times, as the dynamics of 
thermoregulation favor the temporal artery method.

Scanner readings 
are lower than 
current/traditional 
methods; false low 
readings.

• A patient's temperature measured 

with the scanner is normally not 
appreciably lower than oral 
temperature. Lower temperatures 
are usually caused by improper 
scanning techniques.

• A dirty scanner lens may result in 

inaccurate measurement 
determinations.

• Both a sweaty forehead and wet 

behind ear.

• Multiple readings can cool the skin, 

so if you take another 
measurement immediately, expect 
a slightly lower reading.

• The button was released before 

the measurement was complete.

• Slide the scanner 

straight across the 
forehead, not down 
the side of the face. 
Do not scan too 
quickly.

• Keep the probe cone 

flush on the skin.

• Clean the lens.
• Return when patient 

stops sweating. 

• Keep the button 

pressed down while 
scanning.

• Refer to 

on page 12-5 for user 

instructions.

The measurement 
appears on the 
scanner window, 
but does not 
register in the 
monitor.

• The scanner’s connector is not 

secured to the monitor.

• The scanner’s battery cover is not 

secured.

• Loss of electrical contact between 

the scanner and the monitor (e.g., 
corrosion on the connector inside 
the scanner).

• The monitor is not configured to 

interface with an Exergen scanner.

• Confirm the scanner’s connector is secured to the 

monitor.

• Confirm the scanner’s battery cover is secured.
• Contact  service.
