SKYWATCH Wind Pro Windmeter User Guide
Thank you for purchasing this Swiss-designed and Swiss manufactured wind instrument. To obtain the best results, please read the instructions and follow the usage precautions. This instrument is designed as an aid to users who are in an open-air environment, but IT CANNOT replace advice and warnings from the local weather station. Open-air climatic conditions can sometimes change quite dramatically, and this can happen very quickly indeed. Sunny weather can, for example, change to thunderstorm conditions in the space of half an hour and sometimes less. You should therefore always follow basic safety rules whenever you undertake open air activity.

wind speed is measured since the last manual reset (holding the power button
for longer than two seconds resets it to zero). For the measurement to be as
exact as possible align the instrument along the axis of the wind.

MAINTENANCE
The design and manufacture of this instrument have been the subject of a great deal of care. To make best use of the proposed functions you are advised to use the instrument in accordance with the following observations:
- Avoid at all costs items such as hair, thread, sand or other dust materials getting into the impeller, as they could cause defective rotation of the impeller and therefore a loss of precision. If a hair or a piece of thread should manage to get into the impeller, extract it gently using tweezers; in the case of dust or sand, you can run clean water over the impeller.
- Avoid touching the temperature sensor.
- Avoid exposing the instrument to extreme climatic conditions for over-long periods. While it uses components resistant to such temperatures, we recommend that you do not expose your instrument to strong sources of heat, for example under the windscreen of a vehicle.
- Avoid careless use or sharp impacts.
- DO NOT EXPOSE the instrument to powerful chemicals. Such products could damage it.
IMPELLER REPLACEMENT
To replace the impeller gently remove the rear support usinga pair of fine pliers. Insert the new impeller so the magnet is facing to the rear of the unit. Gently press the rear support back into place. Avoid touching the sharp impeller shaft.
