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.

Accuracy is defined as the ability of a measurement to match the actual
value of the quantity being measured.
A hygrometer is a device that measures relative humidity. Relative
humidity is a term used to describe the amount or percentage of water
vapor that exists in air.
Range is defined as the amount or extent a value can be measured.
