Figure 5 Close the chamber with the chamber
cover
6. Fasten the salt chamber on the holder in the base plate
and close the measurement holes with rubber plugs.
The chambers can also be used as individual checkers
without the base plate.
NOTE The plugs have three steps, each of which is suitable for a
certain hole diameter: the first step for the 12 mm, the
second step for the 13.5 mm and the third step for the 18.5
mm hole. Keep the holes always closed when not
calibrating.
7. Write the preparation date on a sticker and mark the
chamber with it. If you use a ready-dosed salt package,
use the sticker with the batch code. Mark all parts of
the salt chamber (chamber, chamber cover and transit
cover) with stickers. This way, various covers and
different salts do not get mixed.
