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.
