The offline calibration feature is simply a one point calibration without
a slope change. The term "offline calibration" refers only to the fact that
a sample from 2120XP analyzer bypass is taken "offline" for laboratory
analysis; in fact, no downtime is experienced and the analyzer remains
online throughout the procedure.
