14. If the instrument passes the test, the hardware diagnostics icon turns green.
If the instrument fails, refer to section 5.1 in the Direct Detect® Software User

13.2 Replacing the Desiccant
Excessive humidity inside the spectrometer may cause H
2
O bands in the spectrum. To
reduce H
2
O bands to a minimum, the air inside the Direct Detect® instrument module is
convectively dried with a desiccant enclosed in a small, removable, multichambered pack.
If the desiccant is saturated and can no longer absorb humidity, it must be replaced.
Both the internal humidity icon (Figure 37) and instrument status light (on top of the
instrument, 5E in Figure 5) will turn yellow. When you click on the internal humidity icon,
a warning message with the current humidity level is displayed (Figure 37).
