Adjusting Electrical Constants 

 

The following constants can be adjusted:

 

·      Zener Voltage;

·      LDR Max Resistance;

·      LDR PullUp Resistance;

·      Rain Beta Factor;

·      Rain Resistance at 25º;

·      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.
