When conducting temperature test, the setting temperature is higher than ambient temperature, it’s better to remove wet bulb gauze, or else the water absorbability will get poorer if the gauze is toasted excessively, which will affect accuracy of humidity measurement. Besides, it’s better to supply water for gauze when conducting temperature test to prevent gauze from being toasted. You can refer to Chapter 5.8 “Detailed Setting of Equipment” in user’s manual; when the temperature is equal to or higher than 120℃, the gauze will be toasted no matter whether to supply water or not.
