(1) Temperature errors can occur when a sensor is placed too close to a heat source
(such as a building structure, the ground or trees).
To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer.
Bi-metal (dial) and digital thermometers (from other weather stations) 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 3 hours. Compare this temperature to the fluid
thermometer and adjust the console to match the fluid thermometer.
