Readings from software logs can be misleading, eg a unit with a broken speed sensor will also show no direction (ie the ‘dashed-out’ symbol) in the software log on the basis that zero wind speed must automatically mean calm conditions with no valid wind direction. *It is always best to diagnose wind issues from readings on the console display (but clearly not possible with an Envoy console). Issues and faults with readings of wind speed and direction tend to fall into one of three categories, each of which is discussed in more detail below: Note: If wind data is being received from a 6332 Anemometer Transmitter rather than direct from the ISS then the possibility of a transmitter issue rather than any anemometer fault should be borne in mind.

Troubleshooting for all of these three anemometer types is much the same, but technical differences and how to tell the difference between them is described on the separate anemometer hardware page. The 7911 anemometer that was used for the WMII and Wizard III stations.The revised 6410 anemometer introduced in 2013 (though not necessarily widely supplied until 2014) and incorporating a replaceable speed bearing and solid-state speed sensor.The original 6410 VP1/VP2 unit that was used for many years from about 2000-2013 with only minor changes during that time.There are actually three types of VP2-type anemometers that have been used in Davis stations: At a technical level, however, the sensing of wind speed and direction is broadly similar on both Vue and VP2 and much the same troubleshooting approach applies to both models, with specific comments on differences in fixing wind issues included below where appropriate. The look of the wind sensors on Vue and VP2 models is obviously fairly different with the Vue’s all-in-one sensor design contrasting with the separate anemometer of the VP2 station. (Strictly speaking, an anemometer measures wind speed only, but a sensor that measures both speed and direction readings is also often referred to as an anemometer.)

These are often also referred to as anemometer issues.

This topic covers issues and faults with readings of wind speed or wind direction.
