Separate slope and offset values are calculated and recorded for H
measurements.
In SO2 Mode they appear as SO2 OFFS & SO2 SLOPE. In multigas mode, both versions
Calibration of the analyzer is performed exclusively in software. During instrument
calibration (Chapters 6 and 7) the user enters expected values for zero and span through
the front panel keypad and commands the instrument to make readings of sample gases
with know concentrations of H
compared to the expected values as input. With this information the software computes
values for instrument both slope and offset and stores these values in memory for use in
calculating the H S concentration of the sample gas.
