FIGURE 19-10 Weather Humidity Menu
When used with a Model 831, with the exception of
precipitation data, the Vaisala weather station is configured
to report measurements once per second. The reported
values are the average over that one second interval. Wind
Gust is the max speed detected over that interval.
The Vaisala will send precipitation information every 10
seconds if precipitation has been detected.
If the Model 831 is configured to include Vaisala weather
data in the Time History, it will be this one-second data,
even if the Time History period is set to something other
than one second. This means that if the TH interval is less
than one second, you will see a repetition of values until it is
updated by the Vaisala. Conversely, if the TH interval is
greater than one second, the reported value will be the
average over the last second only.
Precipitation data is not available in the Time History.
