The Desiccant Indicator
The optical system of the spectrometer is purged at the factory. This protects the
beamsplitter and the sample compartment windows from being damaged by humidity.
Replaceable packs of desiccant keep the optics dry and free of CO

.
The top panel of the instrument includes a desiccant indicator, whose sectors change
sequentially from blue to pink as the desiccant packs are exhausted (Figure 10). Change the
desiccant in the instrument when the sector marked 10 becomes pink, but while the sectors
marked 15 and 20 are still blue.

on page 56 for more information about the
appropriate action to take if the sectors marked 15 and 20 are pink.

CAUTION
If all three sectors of the desiccant indicator are pink, then you must
change the desiccant.
The instrument optics may be fogged. Do not switch the instrument
either ON or OFF until all sectors are blue.
