• Elevated body temperature in the context of use should be confirmed with
secondary evaluation methods (e.g., an FDA approved non-contact
infrared thermometer (NCIT) or a clinical grade contact thermometer)
• Public health officials, through their experience with the device in the
particular environment of use, should determine the significance of any
fever or elevated temperature based on the skin telethermographic
temperature measurement
• The thermal imaging camera should be used to measure only one
subject’s temperature at a time
• Visible thermal patterns are only intended for locating the points from
which to extract the thermal measurement.
RECOMMENDATIONS FOR USING THE THERMAL IMAGER
FOR ELEVATED SKIN TEMPERATURE SCREENING
(Consistent with ISO/TR 13154: 2017 guidelines on thermograph usage)
Preparing the Area where you will use the thermal imaging system
• Recommended room temperature should be 64-86 °F (18-30 °C) with
a relative humidity of 60 percent.
• Try to control other conditions that could impact the temperature
measurement:
• Avoid reflective backgrounds (for example, glass, mirrors, metallic
surfaces) to minimize reflected infrared radiation.
• Set up the thermal imaging camera in a room with minimal movement
of air, out of direct sunlight, and away from radiant heat (for example,
portable heaters, electrical sources).
• Avoid strong lighting (for example, incandescent, halogen and quartz
tungsten halogen light bulbs).
PREPARING THE THERMAL IMAGING SYSTEM
• The 52030F thermal imager does not require the use of a black body
for calibration during evaluation
• Turn on the camera 30 minutes before use.
PREPARING THE PERSON BEING EVALUATED
The person operating the thermal imaging system should make sure
the person being evaluated:
• Does not have any face obstructions during measurement (such as a
mask, glasses, hat, headband, or scarf), the person's hair is pulled away
from the face, and the person’s face is clean and dry.
• Does not have a higher or lower face temperature from wearing excessive
clothing or head covers (for example, headbands, bandanas) or from using
facial cleansing products (for example, cosmetic wipes).
• Has waited at least 15 minutes in the measurement room or 30 minutes
after exercising, strenuous physical activity, bathing, or using hot or cold
compresses on the face.
USING THE THERMAL IMAGING SYSTEM
• Measure only one person’s surface skin temperature at a time.
• Position the person at a fixed distance of 3 feet (1 meter) from the
thermal imaging system, directly facing the camera.
• Recommended viewing angle is approximately 21° vertical x 21°
