Drift
The offset and amplification drift values are calculated
cumulatively starting from the last basic calibration.
Delta drift
The offset and amplification Delta drift values are calculated
between the last and next to last automatic calibration. They are
deleted by manual zero point or end-point calibration.
Note
The drift values are displayed in percent of the customer
measuring range, i.e. the factory-set measuring range (see
Limits of measuring ranges on page 141) (see Analyzer data
sheet on page 15).
The drift values are cleared by a calibration reset.

Air pressure effect
A change in the atmospheric air pressure compared to the
calibration time results in a change in the measured value.
Automatic pressure correction with pressure sensor
If a pressure sensor is installed in the gas analyzer (see
Calibrating the pressure sensor on page 195), automatic
internal pressure correction minimizes the influence of air
pressure changes on the measured value.
Pressure correction with Magnos206 / Magnos28
The Magnos206 / Magnos28 without built-in pressure sensor
has been calibrated at the factory for an air pressure of 1013 hPa.
If the air pressure at the installation site deviates from 1013 hPa,
the current air pressure can be entered manually to correct it.
Impairment of the measuring accuracy of
Magnos206 / Magnos28!
The pressure sensor of Magnos206 / Magnos28 is specifically
adjusted at the factory for measuring ranges with suppressed
zero point.
• A recalibration of the pressure sensor reduces the
measuring accuracy of Magnos206 / Magnos28.
