Description of Non-Contact Infrared Body Thermometer

Device principle and introduction

The non-contact thermometer is a hand-held, reusable, battery operated device, which can measure human body temperature on the forehead.

The operation principle is based on Infrared Sensor technology. The IR sensor can output different signals when measuring different object temperature or in different ambient temperature, and the ASIC can turn the signal from IR Sensor to a digital value and display it on the LCD.

OPERATION

Battery installation

Caution: The Non-Contact Infrared Body Thermometer does not operate with dead batteries and does not input outer power. Install new batteries.

Pull the battery downward, toward the bottom of the Non-Contact Infrared Body Thermometer and remove the battery access door.
Install or replace using 2 AAA batteries in the battery compartment according to the “+” and “-”.
Close the battery cover.

How to Operate

Before Applying the Thermometer

Be sure to read and understand all warnings listed in the instructions before use.

The thermometer is aligned with the middle of the forehead to measure body temperature (between the eyebrows center it above at the forehead level). Keep the vertical distance, press the On/Scan button, the temperature will display immediately, see Figure 2.

Figure 2: Measuring position and distance
When the ambient temperature of the thermometer changes too much, such as moving the Thermometer from one place of lower temperature to another place of higher temperature, allow the thermometer to remain in a room for 30 minutes where the temperature is between 59°F to 104°F (15°C to 35°C).
The ambient temperature around the person should be stable, and be away from fan’s, air-conditioning vents, and so on.
When moving the person from one place of lower temperature to another place of higher temperature, the person should remain in the new environment more than 5 minutes, to be consistent with the ambient temperature for the re-measurement.
Wait at least 1 second for the next measurement. After 5 continuous measurements, it is recommended to wait at least 30 seconds and then continue measurement.
DO NOT use the thermometer in a place where the sun is strong.
If for some reason the forehead temperature is low, a body temperature can be taken behind the ears. See Figure 3.

Figure 3: Align behind the ears to take measurement

General Setup and Use

To take a measurement

Turn on the thermometer by pressing the On/measure button. The thermometer will perform a self-test displaying all segments for 2 seconds.
Align the thermometer with the forehead at the proper distance, and then press the On/measure button to start the measurement.
Read the data.

NOTE: You will hear 3 beeps indicating the measurement is complete, and the temperature will be displayed on the screen. The color of the back light will display either red, yellow, or green according to the result.

Green – Normal temperature (95.9 – 99.1°F / 35.5 – 37.3°C) And the Green means ready for next measurement

Yellow – Slight fever (99.2 – 100.4°F / 37.4 – 38.0°C)
Red – High fever (100.6 – 109.2°F / 38.1 – 42.9°C)

When the result is a high fever, please consult your doctor or physician.

To ensure the accuracy of the measurement, wait at least 30 seconds after 5 consecutive measurements.

Mode Conversion
When the device is running, pressing the MODE button to cycle between “body” mode and “surface” mode.
“body” mode is used for measuring human body temperature, the “surface ” mode is used to measure the surface temperature. (The factory default is “body” mode).
Recalling and Erasing Memory Data
The last temperature taken before the thermometer powers off is stored in memory, up to 50 measurements.

1. In the boot or shutdown state, short press the MEMO button to view the history of measured values.
2. If there are no memories, the display will show “—°F” or “—°C”
3. Temperature readings can be stored in memory. Up to 50 temperature readings can be stored into the memory cells and automatically overwrite historical data.
4. In boot mode, press and hold the MEMO button until the LCD displays “CLR” and you hear a beep. Once deleted, the memories cannot be restored.

Parameter Setting
The thermometer can be adjusted according to the subjects of different colors and different environments data to meet the different characteristics of populations or individuals. Long press the MODE button to modify the measurement parameters.

Unit Set-F1
Under the boot mode long press SET button to enter F1, press the MODE or MEMO button to switch Celsius and Fahrenheit temperature units, and press the SET button to confirm the unit settings (factory default is ) ° .
Fever Alert Set-F2
Under F1 state, press SET button to enter the F2, press the MODE button to decrease 0.1 °C, press the MEMO button plus 0.1 °C, long press to accelerate the speed of temperature regulation, and finally press the SET button to save. (The factory default is 38.1°C)
Prompt Sound Settings-F3
Under F2 state, short press SET button to enter F3, press MODE or MEMO button to set voice switch, and press the SET button to confirm the settings. (The factory default is the voice prompt to open).
Overall Temperature Offset Value-F4
To meet the different colors and characteristics of the population or the environment caused by seasonal tempurature change, is large that need for temperature detection and debugging.
Under F3 state, short press the SET button to enter F4, press the MEMO button to plus 0.1 °C, press the MODE button decrease 0.1 °C, long press fast subtraction temperature, and then SET button to confirm the parameter setting.
Parameter adjustment range: -5°C and + 5°C (factory default is 0).
Exit Setting Mode
In the F4 mode, press the SET button and the screen will automatically turn off, exit setting.
