This thermometer is calibrated and adjusted at the factory. If you are in high altitudes or wish to check the calibration: 
Bring a clean container of water to a boil.
Carefully place the end of the thermometer probe into boiling water past the groove on the lower portion of stem. Leave immersed for at least one minute taking care not to let the probe rest on or make contact with the container.
Boiling point will read 100°C at sea level. Boiling point decreases approx 2° with each 1000’ of altitude. If the thermometer does not read 100°C at sea level, calibration can be reset by carefully holding the thermometer head and turning the hex nut with a wrench to move dial in one direction or the other.
