ABC CALIBRATION ALGORITHM
ABC (Automatic Baseline Calibration) is a patented self-calibration feature that
automatically adjusts the CO2 sensor to compensate for drift. When ABC is enabled,
the lowest reading within every 24-hour period is recorded and analyzed over
a running 7 day or 28-day period. If a statistically significant amount of drift is
detected, an automatic correction factor is applied. This enables the sensor to operate
within specifications for the 5-year calibration interval.
NOTE: After changing the ABC settings, the unit will need to be power cycled for the
changes to take effect.
