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 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.
