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.

To Enter AVG / BLANK Mode

1.Push power button to turn unit on. Wait for power up sequence to finish (30 seconds).

2.Push and hold the unnamed button first, then Push and hold the Menu button. Hold both buttons until the screen goes blank (two seconds). Release both buttons and the unit is now in Programming Mode.

3.Push the MORE button.

4.Push the DISP (display) button and the unit is now in the AVG / BLANK mode.
