Regenerating the Desiccant
The instrument's desiccant canisters can be regenerated by drying them in an oven.
Note
• If you plan to regenerate the desiccant canisters, you will need a second set to place in
the instrument while the first set is being dried.
• If the desiccant canisters are old or damaged,
• If the humidity indicator is no longer blue, the indicator must be replaced. A
replacement indicator is included in the desiccant replacement kit.
Time needed: 3 hours
Tools needed:
• Vented oven
• Insulated cloth or hot pad
NOTICE Make sure the insulated cloth or hot pad you use to handle the regenerated
desiccant canisters is clean. Contaminants in a used cloth or hot pad could be absorbed by
the desiccant and subsequently released into the instrument.
 To regenerate the desiccant
NOTICE Do not leave canisters in the oven for more than three hours and do not exceed
a temperature of 150 °C (300 °F). Allow the canisters to cool completely in a dry
environment before you install them in the instrument.
1. Place the saturated desiccant canisters in a vented oven at 150 °C (about 300 °F) for three
hours.
