The AcuRite Iris® (5-in-1) Weather Station is designed for use in the Northern Hemisphere, however, it can be adjusted for use in the Southern Hemisphere. When using the AcuRite Iris® (5-in-1) sensor in the Southern Hemisphere, the sensor will need to be mounted with the solar panels facing North and the wind vane will need to be modified to read correctly in this orientation.

The AcuRite Iris® (5-in-1) sensor can be used in the Southern Hemisphere by making a modification to the wind vane. This modification effectively reverses the wind vane on the AcuRite Iris® (5-in-1) sensor so when mounting the sensor with the solar cell facing North, it will read correctly in the southern hemisphere.

1. Pull off the wind vane, located on the bottom of the sensor. This will require some force to "pop" it off.
2. Observe the hole in the wind vane (where it attaches to the metal shaft on the AcuRite Iris® (5-in-1) sensor) and notice that it is not a perfectly round hole. Mark the location of the flat spot on the hole in the wind vane.
3. Drill out, or otherwise round out the flat spot in the hole so that it becomes a perfectly round hole in the wind vane. DO NOT enlarge the hole, simply round it out.
4. Line up the hole of the wind vane with the metal shaft on the AcuRite Iris® (5-in-1) sensor, but use your marking on the flat spot (from step 2) to line up the wind vane facing the OPPOSITE way from how it was originally designed. Press the wind vane firmly and carefully on the metal shaft of the AcuRite Iris® (5-in-1) sensor.

The AcuRite Iris® (5-in-1) sensor is now ready for use in the Southern Hemisphere.
