Open the bag protecting the new desiccant pouch and replace it (or install for a new instrument) in the
desiccant tray assembly. Each desiccant pouch is shipped with a HUMONITOR
®
humidity indicator.
Make sure that the area inside the ring is blue and at least as dark as the rectangular reference field
when opening the bag. If this is not the case, the desiccant pouch is not effective (e. g. because of an
untight bag).
Figure 8: Humidity indicator
To speed up the recognition, by the instrument, of the new desiccant it will be necessary to reset the
instrument. To do so, disconnect the sensor interconnect cable for 2 seconds and then reconnect it (see
fig. 4).
Note
Once the bag is opened, install the desiccant pouch immediately to prevent premature
degradation of the desiccant.

Replacing the source lamp
The source lamps in the Turb 2000 series are designed for very long life. If the lamp should need
replacement, we recommend calling WTW service department for assistance.
