Important Safety Instructions 


Intended Use: The Exergen TemporalScanner is a handheld infrared thermometer used by medical 
professionals for the intermittent measurement of human body temperature of people of all ages, by 
scanning the forehead skin over the temporal artery. Intended users are physicians, nurses, and nursing 
assistants at all levels who normally provide patient care. The thermometer provides a peak temperature 
reading from plural readings during the step of scanning. Electronic circuitry processes the measured peak 
temperature to provide a temperature display based on a model of heat balance relative to a detected arterial 
temperature, the electronic circuitry computing an internal temperature of the body as a function of ambient 
temperature (Ta) and sensed surface temperature. Training materials that are supplementary to this 
instruction manual are available at, and recommended for first time users. 

TAT-5000 Series thermometers are used by medical professionals in clinical environments. Such medical 
professionals include physicians, nurses, nurses’ aides, patient care technicians, and others who are trained 
to take the temperature of patients. Clinical environments include areas where medical professionals are 
providing medical services for patients, including hospitals, outpatient clinics, primary care offices, and other 
settings where temperature is taken as part of patient care. Clinical environments include Emergency 
Medical Services environments. 

Additionally, the TAT-5000 series thermometers are not for use aboard aircraft or near High Frequency 
Surgical Equipment or Radio Frequency shielded rooms, such as MRI (Magnetic Resonance Imaging) areas.

Introduction to Temporal Artery Thermometry 

Temporal artery thermometry (TAT) is a unique method of temperature 
assessment, using infrared technology to detect the heat naturally 
emitting from the skin surface. In addition, and of key importance, this 
method incorporates a patented arterial heat balance system to 
automatically account for the effects of ambient temperature on the skin. 

This method of temperature assessment has been shown to improve 
results and reduce costs by non-invasively measuring body temperature 
with a degree of clinical accuracy unachievable with any other thermometry 
method. The temporal scanner is a type BF device. 

Before Using, Familiarize Yourself with the Instrument 

• To Scan: Depress the red button. The instrument will continually scan for the highest temperature (peak) as 
long as the button is depressed. 

• Clicking: Each fast click indicates a rise to a higher temperature, similar to a radar detector. 

Slow clicking indicates that the instrument is still scanning, but not finding any higher temperature. 

• To Retain or Lock Reading: The reading will remain on the display for 30 seconds after button is released. 
If measuring room temperature, the temperature will remain on the display for only 5 seconds. 

• To Restart: Depress the button to restart. It is not necessary to wait until the display is clear, the 
thermometer will immediately begin a new scan each time the button is depressed. 

Alternate sites when temporal artery or behind ear are unavailable: 

• Femoral artery: slowly slide the probe across groin. 

• Lateral thoracic artery: slowly scan side-to-side in the area midway between the axilla and the nipple.

2-Step Infant Temperature Measurement 

Step 1 

Place probe flush on center of 
forehead and depress button. Keeping 
button depressed, slowly slide probe 
mid-line across forehead to the hair 

Step 2 

Release button remove from head 
and read. 

How to improve the accuracy of your measurements on infants 

The preferred site is the 
temporal artery area. Unless 
visibly diaphoretic, one 
measurement here is typically 
all that is required. 

If the temporal artery is 
covered, then the area behind 
the ear, if exposed, can be an 
alternate site. 

Measure straight across the 
forehead and not down side of face. 
At mid-line, the temporal artery is 
about 2 mm below the surface, but 
can go deeply below the surface on 
the side of the face. 

Brush the hair aside if 
covering the area to be 

Measurement site must 
be exposed. 

3-Step Adult Temperature Measurement 

Step 1 

Slide across forehead. 

Place probe flush on center of forehead 
and depress button. Keeping button 
depressed slowly slide probe mid-line 
across forehead to the hair line. 

Step 2 

Slide behind ear. 

Keeping button depressed, lift probe from 
forehead, touch behind ear halfway down 
the mastoid process and slide down to the 
soft depression behind the earlobe. 

Step 3 

Release button and read. 

How to improve the accuracy of your measurements on adults 

Measure only the up-side on a patient 
in a lateral position. 

The down-side will be insulated 
preventing the heat from dissipating, 
resulting in falsely high readings. 

Think of a sweatband. 

Measure straight across the forehead 
and not down the side of the face. 

At mid-line, the temporal artery is about 
2 mm below the surface, but can go 
deeply below the surface on the side of 
the face. 

Measure exposed skin.

How does the temperature from a temporal scanner relate to core temperature? 

Temporal artery temperature is considered a core temperature because it has been demonstrated as accurate as the temperature measured by a 
pulmonary artery and esophageal catheter, and as accurate as a rectal temperature on a stable patient. Rule of thumb: Rectal temperature is 
about 1 °F (0.5°C) higher than an oral temperature and2°F (1 °C) higher than an axillary temperature. It will be easy to remember if you think of 
core temperature as a rectal temperature, and apply the same protocol you would use for a rectal temperature. 

If your thermometer is marked Arterial/Oral and has a serial number beginning with “O” (standard model start with “A”), it is programmed to 
compute the normal average cooling effect at the mouth, and automatically reduces the higher arterial temperature by that amount. This 
calibration allows the hospital to maintain existing protocols for fever workups based on oral temperature, and results in a reading consistent 
with the 98.6°F (37°C) mean normal oral temperature, in the range of 96.6 - 99.5°F (35.9 - 37.5°C). 

What should I do if I get an abnormally high or low reading, how do I confirm my reading? 

• Repeat the reading with the same Temporal Scanner; a correct reading will be reproducible. 

• Repeat the reading with another Temporal Scanner. Two Temporal Scanners with the same reading will confirm the reading. 

• Sequential readings on the same patient in rapid succession will cool the skin; it is best to wait about 30 seconds for the skin 
to recover from the cold probe. 

Possible causes of abnormal readings. 

Type of 



Possible cause 

Helpful hint 

Dirty Lens 

Clean lens of scanner every two weeks. 

Releasing the button before 
finished measuring 

Release the button after finished measuring. 

Measuring when an ice pack or wet 
compress is on the forehead 

Remove ice pack or wet compress, wait 2 minutes, and re¬ 
take temperature. 

Abnormally low 

Measuring a completely 
diaphoretic patient 

Complete diaphoresis includes diaphoresis of area behind the 
ear and suggests that the temperature is rapidly dropping. 

Use an alternative method of temperature measurement in 
these cases until the patient is dry and the temporal artery 
measurement can be repeated. 

Improperly scanning down the 
side of the face 

Scan straight across forehead. The temporal artery is closest 
to skin in that area. 

Abnormally high 

Anything covering the area to be 
measured would insulate and prevent 
heat from dissipating, resulting in false 
high readings. 

Confirm measurement site has not recently been in contact 
with heat insulators such as hats, blankets, and hair. 

Scan the area not covered or wait about 30 seconds for the 
previously covered area to equilibrate to the environment.

Care and Maintenance 

• Battery: A standard alkaline 9V battery provides approximately 15,000 readings.** To 
replace, loosen the single screw at the bottom of the instrument and remove the battery 
cover. Disconnect the old battery and replace with a new one in the same location. 

Replace the cover, and tighten the screw. Use only high quality alkaline batteries. 

• Handling: The Temporal Scanner is designed and built to industrial durability standards 
in order to provide long and trouble-free service. However, it is also a high precision 
optical instrument, and should be accorded the same degree of care in handling as you 
would provide other precision optical instruments, such as cameras or otoscopes. 

• Cleaning the case: The TemporalScannercase can be wiped down using a cloth 
dampened with 70% isopropyl alcohol. The industrial grade housing and design of the 
electronic components allow for completely safe cleaning with 70% isopropyl alcohol but 
should not be immersed in fluid or autoclaved. 

• Cleaning the sensor lens: With normal use, the only maintenance required is to keep the lens 
on the end of the probe clean. It is made of special mirror-like, silicon infrared-transmitting 
material. However, dirt, greasy films or moisture on the lens will interfere with the passage of 
infrared heat and affect the accuracy of the instrument. Regularly clean the lens with a cotton 
swab dampened with an alcohol wipe. Use only light force for cleaning, to avoid damaging the 
lens. Water can be used to remove any residual film left by the alcohol. Do not use bleach or 
other cleaning solutions on the sensor lens. Use 70% isopropyl alcohol. 



• Calibration: Factory calibration data is installed via a computer which communicates with the TemporalScanner’s 
microprocessor. The instrument automatically self-calibrates each time it is turned on using this data, and will never 
require recalibration. If readings are not correct, the instrument should be returned for repair. See instructions of the 
return process. 

Instructions for Fahrenheit or Celsius Conversion 

The TemporalScannercan be used in either °F or °C. The TemporalScannerwill come preset based on your preference at the 
time of purchase. To convert from one scale to the other, the only tool necessary is a small screwdriver. 

For °F/°C Conversion: 

• Loosen single screw on bottom of case and remove battery cover. 

• Remove battery. 

• Locate the switch to the right of the battery (shown in the drawing), and 
with the tip of the screwdriver, slide up or down to the desired scale. 

• Remove the screwdriver. 

• Replace battery and cover. 


If repair is required: 

• Contact Exergen at (617) 923-9900 or for a Return Materials Authorization (RMA) Number. 

• Mark the RMA number on the outside of your package and packing slips. 

• Include a description of the fault if possible. 

• Send the instrument to: 

Exergen Corporation 
400 Pleasant Street 
Watertown, MA 02472 USA 

• Include the address the instrument should be returned to.
