Description
Concentration units for user
interface.
ON pegs negative concentrations
at zero; OFF permits negative
concentrations
Dilution factor. Used only if is
dilution enabled with
FACTORY_OPT variable.
Duration of dark cal. First two-
thirds is stabilization period; final
third is measure period.
Dark offset for measure reading.
Dark offset for reference reading.
ON enables CO compensation;
2
OFF disables it.
CO concentration to
2
compensate for.
ON enables source drift
compensation; OFF disables it.
Source drift compensation rate of
change.
CO calculation constant.
CO calculation constant.
Electrical test gain factor for
measure reading.
Electrical test gain factor for
reference reading.
