-Degree Day Counter 

 

This screen shows the information for Degree Day Coun-
ter #1.  This counter is using a temperature range of 50 to 
86°F.  So far it has accumulated 16 Degree Days (DD) for 
today’s  date  and  has  accumulated  2125  since  the  counter 
was started or reset on July 3.  Degree Days calculated by 
the meter are not saved in memory.  SpecWare uses stored 
temperature data to produce its own Degree Day reports.
