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 www.exergen.com/s and recommended for first-time users.
The TAT5000S 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 the temperature is taken as part of patient care. Clinical environments include  Emergency Medical Services environments.
Additionally, the TAT5000S 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.

Care and Maintenance

  • Battery: A standard alkaline 9V battery provides approximately 15,000 readings. ** To replace, insert the end of a bent paper clip into the pinhole on the side of the unit to release the battery compartment door. Disconnect the old battery and replace it with a new one in the same location. Replace the cover. Use only high-quality alkaline batteries.
  •  Handling: The TemporalScanner 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 TemporalScanner case 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 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 that 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 the repair instructions below for the return process.

Instructions for Fahrenheit or Celsius Conversion

The TemporalScanner can be used in either °F or °C. The TemporalScanner will 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:

  • Insert the end of a bent paper clip into the pinhole on the side to release and remove the cover. Remove the battery from the compartment.
  • Locate the switch in the battery compartment (shown in the photo), and with the tip of the screwdriver, slide left or right to the desired scale.
  • Remove the screwdriver.
  • Replace battery and cover.

If repair is required:

  • Contact Exergen at (617) 923-9900 or [email protected] 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.


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 and 2°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 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 abnormal temperature Possible cause Helpful hint
Abnormally low temperature Dirty Lens The clean lens of the scanner every two weeks.
Releasing the button before finished measuring Release the button after finishing measuring.
Measuring when an ice pack or wet compress is on the forehead Remove ice pack or wet compress, wait 2 minutes, and retake temperature.
Measuring a completely diaphoretic patient Complete diaphoresis includes diaphoresis of the 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 the forehead. The temporal artery is closest to the skin in that area.
Abnormally high temperature Anything covering the area to be measured would insulate and prevent heat from dissipating, resulting in falsely 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.
