To calibrate temperature, we recommend a mercury or red spirit (fluid)

thermometer. Bi-metal (dial) and other digital thermometers are not a good

source and have their own margin of error. Using a local weather station in your

area is also a poor source due to changes in location, timing (airport weather

stations are only updated once per hour) and possible calibration errors (many

official weather stations are not properly installed and calibrated).

Place the sensor in a shaded, controlled environment next to the fluid

thermometer, and allow the sensor to stabilize for 48 hours. Compare this

temperature to the fluid thermometer and adjust the console to match the fluid

thermometer.
