If this is the case, the aperture size and the measuring distance should be stated on the report of calibration.

How to calibrate a infrared thermometer. Short of using a black body, the next best way to calibrate your infrared thermometer is to use a simple, inexpensive infrared comparator cup.

Some infrared thermometers will need to be calibrated with an aperture. Wait for the thermometer to register; It is best to calibrate your infrared thermometer.
