This setting can include any integer value within the
following range:
0 to 9dB
LOG and SSA Wind/Tach Settings
Other transducers providing similar
pulse trains and DC voltages
representing measured parameters
could also be utilized in this manner.
For example, engine tachometers
frequently output such pulse trains
and throttle position indicators
usually output DC voltages. The
setup permits the selection of units
for both parameters which would be
consistent with this alternative to
windspeed/wind direction.
This feature is used most frequently with external weather
transducers providing an analog pulse train whose frequency
is proportional to windspeed and a DC voltage proportional
to wind direction. However, other transducers could be
utilized as explained in the left column. In the following
description, it shall be assumed that windspeed and wind
direction transducers are being used.
For the LOG instrument, these data are logged with the
Daily, Advanced Time History, Interval and Exceedance
records as selected by option settings.
For the SSA instrument, these data are logged with the
Advanced Time History and Interval records as selected by
option settings.
