You will only see Dew Point when your temperatures are between 79-40°. Heat index will show above 80° and Wind chill below 40°. You cannot choose what shows on the display unit. Please let us know if you have any other questions. Thank you and have a great day!
Thank you for the clarification. Follow-up question regarding placement of the sensor. I have it placed on top of a wooden fence (6 feet+height of sensor) and today I noticed the temperature spike during sun breaks today. That tells me the temperature is showing an inaccurate reading. How do I fix this?
