This model uses Automatic Background Calibration Logic, or
ABC Logic, a patented self-calibration technique designed to be
used in applications where concentrations will drop to outside
ambient conditions (approximately 400 ppm) at least three
times in a 14 day period, typically during unoccupied periods.
With ABC Logic enabled, the sensor will typically reach its
operational accuracy after 25 hours of continuous operation
if it was exposed to ambient reference levels of air at 400 ±10
ppm CO
2
. The sensor will maintain accuracy specifications with
ABC Logic enabled, given that it is at least four times in 21 days
exposed to the reference value and this reference value is the
lowest concentration to which the sensor is exposed. ABC Logic
requires continuous operation of the sensor for periods of at least
24 hours.
