Preparing the Anemometer
Refer to this section in your ISS Installation Manual.
Preparing the ISS for Installation
The radiation shield must be partially disassembled in order to make power
connections for either the solar panel or AC-power adapter, and to install bat-
teries in solar-powered models.
Preparing the Rain Collector
Follow these steps to prepare the rain collector for operation and to begin dis-
assembling the radiation shield.
1. Remove the rain collector cone from its base by rotating the cone counter-
clockwise until its latches line up with openings which allow you to lift it
off. The cone fits in the base tightly and may require extra pressure to
remove it when new.
Tip: Steady the base between your knees when you rotate the rain collector.
Note: If installed, the UV and solar radiation sensor cables are routed through the
base of the rain collector. Please make sure they do not get moved and make
sure they do not interfere with the tipping bucket mechanism or with latching
the cone back onto the base.
2. Carefully cut and remove the plastic cable tie (usually black in color) that
holds the two-sided tipping bucket mechanism in place during shipping.
