5.2 Check to ensure the indication accuracy and leak-tightness
of the device
The indication accuracy and the leak-tightness of the device must
be checked at least once a year.
SEWERIN recommends that these tests also be performed if any
irregularities occur during measuring or the measuring results
are inexplicable.
Checking the leak-tightness of the device means cheaking that
the MiniLec 4 itself is leak-tight. This check must not be confused
with the leak test (see section 3.1.4).
Both tests are carried out using a MiniLec 4 tester (see sec-
tion 7.6.2).
