Changing the Desiccant
CAUTION
Expect to change the desiccant
in the
spectrometer every six months.
Old, used desiccant releases moisture.
In regions experiencing high humidity levels we recommend that you
change the desiccant more often.
The desiccant change interval is set in the
Desiccant change due in (days)
option on the
Setup Instrument BeamPath tab in Spectrum software (Figure 29).
Figure 29 Setup Instrument BeamPath tab in Spectrum
If an instrument desiccant change is overdue, a warning will be displayed in the Status Bar
and in the Setup Instrument BeamPath table.
The warning is displayed until you tell the software that the desiccant has been changed. To
reset the desiccant change interval, select the current value, click Changed to clear any
warning messages, and then enter the number of days before the next desiccant change is
due.
