Calibration
Offline Calibration
Procedure
The offline calibration feature is simply a one-point calibration without
slope change. The term “offline calibration” refers only to the fact that
a sample from 2110XP bypass is taken “offline” for laboratory analysis;
in fact, no downtime is experienced and the instrument remains online
throughout the procedure.
