⚫ The calibration parameter has a great influence on the
measurement precision, so the calibration parameter
should be reset when the precision has a large error during
the use;
⚫ This work should be carried out with the assistance of a
person of normal body temperature.
Step 1: Let the assisting staff stand 1 meter from the thermal
imager and measure his temperature of forehead with the
