During the DUT calibration, the DUTs reading is compared with the highly accurate relative humidity measured with the chilled mirror system. A chart is used to convert the difference in temperature between the regular thermometer and the water-soaked thermometer as the temperature difference is rated to the evaporation rate which is related to humidity. A chilled mirror hygrometer is often used for this purpose. Similarly, using different amounts of water may also give you different results. A plethora of tutorials and how-to guides on how to do this can be found on the internet. For instance, some devices let you record the humidity every hour.
