Adjusting Electrical Constants 


The following constants can be adjusted, if for any reason the factory settings have been lost (memory failure...):


      Zener Voltage;

      LDR Max Resistance;

      LDR PullUp Resistance;

      Rain Beta Factor;

      Rain Resistance at 25;

      Rain PullUp Resistance;


These constants affect the brightness sensor value and the rain sensor temperature value, respectively.


The adjustments should be used to account for the manufacturing tolerances inherent to these components (typically 5%).


In order to adjust these values, select Device TAB / section Constants and then right-click with mouse in the area highlighted in the following figure and corresponding to the constant one wishes to adjust.




A small window will automatically open, allowing the value to be changed.
