Let the thermometer and individual being measured acclimate to the temperature of the room in which the measurement will be taken.
The thermometer needs to acclimate to the room temperature for 10 minutes before taking a measurement.
The individual being measured should be indoors for 30 minutes before taking a measurement. External temperature can impact skin temperature.
Ensure that the individual’s forehead is prepared for measurement.
Wipe away any sweat with a dry cloth. Sweat can cool skin resulting in a false reading.
Ensure that the forehead is clean. If you clean the forehead, wait 10 minutes before taking a measurement.
Hair can insulate the forehead and make it slightly warmer. Make sure to move hair away from the forehead and wait 10 minutes before taking a measurement.
