6 Other Console Functions
6.1 Historical data storage
The console can record historical weather data when an appropriate
microSD card is inserted in the slot available for this purpose. This is an
optional feature so there will be no problem if you do not install a card.
If you wish to install a card you should use a microSD card. Capacity of this
card is not critical, nor is its “speed class.” Historical data will be written
less often than once a minute, and this is why speed is not critical. While
there is no minimum card size, you can take some guidance from the fact
that a 1 GB card can store in excess of 10 years’ worth of recorded data.
The card should be formatted in MS-DOS FAT format before inserting it in
the slot; Most cards come pre-formatted this way.
Insert the card and press with your finger until you feel a slight “click.” A
correctly installed card will be almost flush with the console housing,
protruding by one or two finger nail thicknesses.
6.2 Beaufort Wind Force Scale
If you have selected the use of Beaufort wind speed units, you can use the
table below for reference. The Beaufort scale is based on qualitative wind
conditions and how they would affect a ship’s (frigate) sails (so yes, it is an
“old” standard). It is therefore less precise than the other scales but is still in
use in various locales.
