Measuring Human Temperature 

 
Taking a Measurement 
1. Press the Power Button to power on the thermometer. The unit will 

run a self-test and the LCD will briefly display all of its symbols during 
this time. When the device is ready, “--“appear on the screen, and 
the thermometer is ready to take a measurement. 

2. Select the desired mode by pressing and releasing the Human/Object 

Button.   

Note: 
-   When taking a patient’s temperature, ensure that the thermometer 

is in Human Mode; the Human symbol “ ”will appear on the 
display. 

-  If the patient’s skin is covered with hair, sweat, or dirt, clean the area 

and wait 10 minutes before taking a measurement. 

-  Ensure that the thermometer is held firmly during measurement and 

that the patient does not move until the measurement is complete. 
Movement can impact the measurement. 

3. Position the thermometer under 3cm (around 1 inch) from the center 

of the patient's forehead with the sensor aimed between the 
eyebrows. 

4. Press and release the Measure Button. 
5. Slowly move the device toward or farther from the forehead until you 

have reached the correct distance. (If the distance is beyond the 
correct distance, the dash-icon on the display flashes in this sequence 
until the correct distance is achieved.)
