PRODUCT NUMBER: THDG986
Non-Contact Infrared Human
Forehead Thermometer Instructions
This is a non-contact infrared thermometer applicable to forehead measurement. The thermometer measures body temperature by collecting heat
radiation emitting from forehead. New probe structure is adopted in this thermometer. It’s a simply operated, hygienic, reliable and highly accurate
thermometer. Users can get precise reading within one second by one touch. This thermometer is cost-effective and is widely used in schools,
customs, hospitals and for family use.
This thermometer is also capable of measuring object temperatures ranging from 32°F–199.4°F (0°C–93°C).
This thermometer is classified as a Class II Medical Device, sorted as internally-powered equipment and type B application device. Water proof
rating is: IPXO. It is prohibited to use this thermometer in flammable anesthetic gas or gas mixture of air and oxygen or nitrous oxide. This is a
continuous operation equipment. It is classified as II a by EU.
Any object can generate a certain portion of infrared radiant energy per its own temperature. The radiant energy and its wavelength distribution
are subjected to its surface temperature. Based on this principle, this thermometer is designed to detect infrared radiation at 5 –14um by a highly
precise infrared sensor made in Germany. By adopting this high quality sensor plus special calculation and calibration, this thermometer is able to
take accurate body temperature.
• Adopting reliable sensor made in Germany
• All-new, patented probe design to ensure high accuracy
• Excellent adaption to ambient temperature. Accurate and reliable even under complicated surroundings
• Measurement mode for human body and object available, one button to switch measurement mode
• Beeper for fever or high temperature
• °C or °F reading available
• Automatic shut-off
• Storage of last 10 readings
• LCD with 3 backlight color options for easy reading
Effective Distance 5cm – 8cm

FUNCTION OF THE SETTING BUTTONS
SETTINGS
User can change reading scale between Celsius and Fahrenheit, and change measurement mode between
human body mode and object mode.
MEASUREMENT MODE SETTING:
When thermometer is on, it displays current measurement mode (Figure 1.1). Press the “Mode” button to
change measurement mode (Figure 1.2).
READING SCALE SETTING:
When thermometer is on, it displays current reading scale. Press the “C/F” button to select reading scale.
NOTICE:
• Temperature under human body mode is obtained from dynamic compensation of environmental temp
and forehead surface temp.
• Object temperature mode is to test surface temperature of an object. The temperature taken from
forehead in this mode is merely the temperature of forehead surface but not body temperature.

MEASUREMENT SETTINGS
BODY TEMPERATURE:
1. Press measurement button to turn on thermometer and display boot screen (Figure 2.1). After POST and two beeps, it will display value of last
reading and be ready for measurement (Figure 2.2).
2. Make sure the thermometer is set to body mode.
3. Keep distance 2"–3" (5–8 cm) from the thermometer probe to the middle of the forehead (figure 2.5). Press measurement button and
thermometer will give a “beep” to indicate measurement is finished and value will be displayed (figure 2.3). If measurement value exceeds
alarm value (default value is 100.4°F or 38°C), it gives three consecutive “beeps” as indication.
4. After measurement is taken, if the thermometer is idle for 30 seconds, it will display “OFF” (figure 2.4) and give a “beep” before shutting off
automatically.
NOTICE:
• Keep the sensor and probe cavity clean before use and after use.
• To ensure the accuracy of measurement, it is recommended to start measurement ten minutes after carrying the thermometer to a new environment.
• Wait for 10 minutes to measure body temperature after measuring objects with extremely high or low temperatures.
• Wait for 5 minutes to start a measurement when a measuring target (object or human) is from an environment with a significant difference in
temperature.
• Breezes, water, sweating or cosmetics on forehead may affect measurement. Do not measure body temperature within 30 minutes after
exercise, bath or meals.
OBJECT TEMPERATURE:
1. Press measurement button to turn on thermometer and display screen (Figure 3.1).
2. Make sure the thermometer is set to object mode.
3. Keep vertical distance 2"–3" (5–8 cm) from the object to the measurement probe. Press measurement button and thermometer will give a
“beep” to indicate measurement is finished and value will be displayed (Figure 3.2). If measurement value exceeds alarm value (default value
is 100.4°F or 38°C), it gives three consecutive “beeps” as indication.
4. After measurement is taken, if the thermometer is idle for 30 seconds, it will display “OFF” (Figure 3.3) and give a “beep” before shutting off
automatically.
NOTICE:
• The value under this mode is object surface temperature instead of core temperature.
• The default value of edinfrared emissivity is 0.95. The reading will deviate from the real temperature because of different emissivity. For
example, the reading on stainless steel is obviously lower than the real temperature. BE CAUTIOUS FOR SCALDING.

EXCEEDING MEASUREMENT RANGE IN BODY MODE:
• When measurement value is lower than 95°F (35°C), it displays Lo (Figure 4.1) and gives 4 consecutive beeps and the backlight on the LCD
screen will turn red.
• When measurement value is higher than 109.2°F (42.9°C), it displays Hi (Figure 4.2) and gives 4 consecutive beeps and the backlight on the
LCD screen will turn red.
EXCEEDING MEASUREMENT RANGE IN OBJECT MODE:
• When measurement value is lower than 32.4°F (0.2°C), it displays Lo (Figure 4.3) and gives 4 consecutive beeps and the backlight on the LCD
screen will turn red.
• When measurement value is higher than 199.4°F (93°C), it displays Hi (Figure 4.4) and gives 4 consecutive beeps and the backlight on the
LCD screen will turn red.
NOTICE:
• When surrounding temperature is lower than 60.8°F (16°C) or higher than 104°F (40°C), it displays Err (Figure 4.5) and gives 4 consecutive beeps
and the backlight on the LCD screen will turn red. Under this condition, it is not advised to use this thermometer and accuracy is not assured.

Description Solutions
LCD Display “Lo” or “Hi”
• Breezes, water, sweating or cosmetics on forehead may affect measurement.
• If the testing environment changes drastically or if the thermometer is used directly
from high temp objects to very low temp objects, the measurement difference may
be inaccurate. The thermometer should be kept in a relatively stable environment for
10 minutes in order for heat to balance before starting a new measurement.
• Ensure measurement distance is 2–3 in. (5–8 cm).
No response when pressing measurement button Take out and reinstall batteries.
No display or improper display Take out and reinstall batteries again.
Shut off right after switching on Check battery level or take batteries out and reinstall.
