1. Be 15 feet from the building

2. Terminate in a T

3. Have 2 pickup points at least 20 feet apart attached to either side of the T

4. Each point should be covered with a flat plate or box

These steps will reduce the magnitude and variation of the Baseline pressures your gauge will see.

After that, time averaging or long Baseline recordings will reduce the impact of these wind pressures.

Detailed instructions for dealing with fluctuating wind can be found in Troubleshooting Error!
