4.2 Display Variables
The Honeywell EC-P2 has two adjustable display variables. These variables control
signal conditioning of the LCD display. Variables are stored on each SMART-CELL.
The AVG (Average) variable determines the number of one second samples to
average to calculate the displayed value. The lower the averaging value, the faster
the display will change and the more “wiggle” will be displayed. The BLANK (zero
blanking) variable controls the lowest reading that will be displayed. This is to
eliminate the misleading display of signals within the zero noise of the sensor. The
following procedure will change the AVG variable.
