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 CO2 compensation; OFF disables it.

CO2 concentration to 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.
