You set the WSO100 wind damping period using Maretron's DSM250 display in the following way. Enter menu mode, scroll to "Configuration…" and press enter. Scroll to "Device Configuration…" and press enter. Scroll to the row containing the WSO100 and press enter. Scroll to "Wind Data Damping Period:" and press enter. Set the damping period lower to see very quick changes in wind speed and direction or set the period higher to smooth out wind readings. The damping period is actually a moving average filter so you must be careful not to set the period to high because this introduces latency or delay in the reported wind speed and direction.
