Description:
|
||
|
|
Contaminants build-up in the measurement chamber or optical
|
||
|
|
elements deterioration leads to sensor drift.
|
||
|
|
|
||
|
|
One can compensate for sensor drift by using automatic self
|
||
|
|
calibration procedure (asc).
|
||
|
|
|
||
|
|
Writing 1 or 0 to this attribute will respectively activate or
|
||
|
|
deactivate asc.
|
||
|
|
|
||
|
|
Upon reading current asc status is returned.

Description:
|
||
|
|
Contaminants build-up in the measurement chamber or optical
|
||
|
|
elements deterioration leads to sensor drift.
|
||
|
|
|
||
|
|
One can compensate for sensor drift by using forced
|
||
|
|
recalibration (frc). This is useful in case there's known
|
||
|
|
co2 reference available nearby the sensor.
|
||
|
|
|
||
|
|
Picking value from the range [400 1 2000] and writing it to the
|
||
|
|
sensor will set frc.
|
||
|
|
|
||
|
|
Upon reading current frc value is returned. Note that after
|
||
|
|
power cycling default value (i.e 400) is returned even though
|
||
|
|
internally sensor had recalibrated itself.
