8 Calibration
A calibration checks and adjusts the measurement accuracy
with a known test gas concentration. First the zero point of the
sensor and then the sensor span is calibrated. Calibrations
have to be performed on a regular basis. The length of
calibration intervals depends on the ambient conditions in
which the sensor is operated.
