Preparing the ISS for Installation
4
4. Slide the tooth-lock washer and hex nut onto the machine screw. Tighten the hex nut
while holding the screw with a Phillips head screwdriver to prevent it from turning.
5. Press the sensor cable firmly and completely into the zig-zagging channel in the base,
starting from the arm and progressing downward to the bottom of the base. Be sure to
press the cable into the channel at the bottom of the groove.
Note:
The pole can pinch or cause wear on the anemometer cable if the cable is not pressed
completely into the channel at the bottom of the groove.
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.
3. Push the wind cups up onto the anemometer’s stainless steel shaft.
4. Slide the wind cups up the shaft as far as possible.
5. Use the Allen wrench provided to
tighten the set screw on the side
of the wind cups.
The wind cups should drop
slightly when you let go.
6. Spin the wind cups.
If the wind cups spin freely, the
anemometer is ready and can be
set aside while you prepare the
rest of the ISS for installation.
Note:
If the wind cups don’t spin freely, take off the wind cups and repeat the wind cup installation
process.
