Preparing the ISS for Installation: Assemble the Anemometer

Attaching Anemometer Arm to Base

1. Insert the anemometer arm into the base, sliding the cable through the notch in the

base as shown in illustration.
Be sure to line up the small hole in the arm with the holes in the base.

2. Insert the machine screw through the holes in the base and arm.
3. Slide the flat washer, tooth-lock washer and hex nut onto the machine screw. Tighten

the hex nut while holding the screw with a Phillips screwdriver to prevent it from turn-
ing.

4. PRESS the sensor cable firmly and completely into the zig-zagging channel in the

base, taking up any slack between arm and base.

Note: The U-bolt used to mount the ISS can pinch or cause wear on the anemometer cable if the cable

is not pressed completely into the channel,.

Attaching the Drip Ring and Wind Cups

The drip ring attaches to the bottom edge of the anemometer head to help protect the
wind cups from icing over. Install the drip ring first, then install the wind cups.

1. Place the black plastic drip ring on the bottom edge of the anemometer head. Gently

push the drip ring onto the head until it clicks into place.

2. Make sure the lower edge of the drip ring is aligned with the lower edge of the ane-

mometer head.
