*Self-Calibration
Feature:
User "self-calibration" will
not restore the sensor to precise values, but
it may improve general sensor accuracy. The
sensor is sensitive to temperature, humidity,
and air quality and the sensor readings may
be affected. Self-calibration does not reliably
maintain accuracy over a long period. |
