3.4 Sealing and Desiccating the Enclosure
The T.Weather 106 Enclosure is supplied with a desiccant pack. The desiccant
maintains a low humidity in the enclosure to minimize the chance of
condensation on the instrumentation. Desiccant should be changed when the
internal T.Weather 106 Enclosure humidity sensor measures 30% or higher.
Install the desiccant as shown in Figure 3.4-1. Keep unused desiccant tightly
sealed in an airtight container.
1)
Take the desiccant pack out of its sealed plastic bag. Place it under the
desiccant strap just before leaving the station.
2)
Be sure to close the enclosure hasp securely. A padlock may be used on
the latch for extra security.
