2.2.5 LINEARIZATION MENU
The linearization menu allows each channel to have its own linearization curve stored in
the controller’s non-volatile memory. Input versus output points must be entered in
percent of full scale values. This means if the range is 0-200 ppmH2S then 100 ppm is
50% of full scale. Zero input will provide a zero output and 100% input a 100% output.
Nine intermediate points may be entered to define the curve.
