Replacing the desiccant
The optical components of your instrument are protected by two desiccant canisters that
absorb moisture. As long as the humidity indicator on your instrument's main cover is blue,
the desiccant canisters are not saturated and do not need to be replaced. When the desiccant
canisters become saturated, the humidity indicator turns pink or white. This means you must
replace the desiccant cartridges.
Notice: We recommend that you maintain seal and desiccation and/or purge your instrument
at all times. Equipment damage due to failure to maintain seal and desiccation and/or purge is
not covered under the warranty. If you have questions about this requirement, please contact
us.
Time needed: 3 minutes or less
Tools needed: 4-in1 tool (included with your instrument)
Note: To order parts, contact us.
Notice: Make sure nothing falls into the instrument while the desiccant cover is removed.
1.—Open the tool compartment, and use the 4-in-1 tool, with the large Philips bit installed, to
loosen the captive screw in the desiccant cover.
Lift off the desiccant compartment cover and put it in a safe place.
