Product Information

In order to ensure the accuracy of the measurement and the safety of use, please read the instructions carefully.

In the early stages of fever, vasoconstriction may occur, and the temperature of the skin surface decreases. At this time, the measured temperature may be abnormally low.
If the measurement result does not match the individual’s diagnosis or the measured temperature seems abnormally low, repeat the measurement every 15 minutes or take another temperature in a different core zone of the body to calibrate the measurement result.

Features

Taking Temperature Measurements

This Infrared Thermometer measures the infrared radiant energy on the forehead or the ear of the human body and converts it into the corresponding body temperature value.

There are 2 modes for measuring temperature. You can switch between these 2 modes by pressing the “ ” button to toggle between the modes:

Body Temp = for measuring a person’s temperature
HOLD = for measuring an object’s temperature

Point the thermometer sensor to the desired surface (1-20mm distance) and press the scan button for approx. 3 seconds for a reading
When the reading is complete, the thermometer will beep and the temperature will be displayed on the LED screen.
To switch between °F Fahrenheit or °C Celcius mode for the reading, press the “ ” button to toggle back and forth.
When the temperature of an individual is too high, in BODY TEMP mode, above 42°C / 107.6°F, the LED screen will illuminate red and show that the temperature is “HI” instead of reading a value.
When the temperature of an individual is too low, in BODY TEMP mode, below 32°C / 89.6°F, the LED screen will show that the temperature is “LO” instead of reading a value.
After approximately 40 seconds of non-use, the thermometer will turn off and go into battery-saving mode.

Taking Temperature Measurements

(continued)

Press the “SCAN” Button or aim the thermometer and press the “SCAN” button to take a temperature or to turn it back on.
Temperature History

The unit will automatically store temperature readings up to 32 times

To view temperature history, hold down the “MODE” button for 3 seconds until you see “LOG” displayed on the bottom left comer of the screen
Use the “ ” or “ ” buttons to read the previously scanned temperature readings (up to 32 readings)
To exit the temperature history, press the “MODE” button for 3 seconds

Tips for Accurate Measurements

Ensure the temperature sensor is clear of dirt or dust
Ensure the forehead is clean and dry
Ensure the individual’s temperature has not been affected by exercise or extreme emotions prior to temperature readings
Do not hold the thermometer for an extended period of time as it is sensitive to heat
If the thermometer or the individual has been transferred from one place to another where the ambient conditions are different, wait for a minimum of 30 minutes before use
Before checking an object’s temperature, clean its surface with a dry, soft cloth
