13.9.3. CALIBRATION - SLOPE AND OFFSET
Calibration of the analyzer is performed exclusively in software. During instrument
calibration, (see Sections 9 and 10) the user enters expected values for zero and span via
the front panel touchscreen control and commands the instrument to make readings of
calibrated sample gases for both levels.
The readings taken are adjusted, linearized and compared to the expected values.
With this information, the software computes values for instrument slope and offset
and stores these values in memory for use in calculating the NO
x
, NO and NO
2
concentrations of the sample gas.
The instrument slope and offset values recorded during the last calibration can be
viewed via the instrument‟s front panel (see Section 4.1.1).
