Outdoor Humidity goes to dashes when temperature is cold.
 The outdoor temperature/humidity sensor designed to work with this weather station
may drop the outdoor humidity and dew point reading in cold temperatures.
 The humidity and dew point will return when the temperature rises. This is how the
sensor came from the factory. The temperature itself will continue to read.
Outdoor sensor fell. The sensor no longer works
Explanation: If there is no physical damage to the outdoor sensor, the fall may not have
caused internal damage. A fall can shock the outdoor sensor or the batteries in the outdoor
sensor. Batteries that have fallen on a hard surface may be damaged and unable to function
properly.
 Complete a Restart
with fresh batteries.
 Use Batteries dated at least six years in advance of the current year. Batteries dated
earlier than six years from now may still work, but may be unstable in performance.
Note: An outdoor sensor that has fallen into puddle, snow, or other standing water, will
likely have water damage and need replacement. Outdoor sensors are water resistant, not
waterproof.
