Tilting frame
The barometer is mounted in a separate wooden case, tilting frame. It
can be set to three different positions: horizontal, ~20° and ~40°. For a
tabletop use, the tilting frame can be removed from the case by lifting
upwards.
NOTE
The pressure connector has to be removed before closing the wooden
carrying case.
Battery
The battery gives a twelve-hour service period. The period is even
longer if the back light is not used. Recharging lasts about 12 hours and
is therefore typically done overnight.
