ABC Logic™ Self Calibration System
ABC Logic™ (Automatic Background Calibration) self calibration
allows the sensor to continually recalibrate itself when the indoor
concentrations drop to outside levels while the building is unoccupied.
Generally a building must be regularly unoccupied for 4 hours or more
for this self-calibration system to operate properly. Under these
conditions, ABC Logic™ should maintain sensor calibration over the
lifetime of the sensor. The ABC Logic™ should be turned OFF where a
building is continuously occupied 24 hours per day, or where there could
be significant sources of non-occupant related CO
breweries and other industrial and food processing applications.
