The testing procedure should be carried out
with meters that are cleaned properly, i.e. after
good parlour cleaning cycle.
The purpose of the periodic checking is to
determine whether the MM27BC is still func-
tioning as it did at the time for the installation
and calibration. Reference values and infor-
mation shall be noted at the time for calibration
of the MM27BC milk meter. The new values
at the time for the periodic check should be
noted and compared with the initial values. See
Chapter 3.1 "Periodic routine test form."
.
If one or more out of the mentioned tests fail,
the meter should be cleaned, checked again
and replaced.

A test probe belongs to each installation
and should be contained on the premises, safe
from mechanical damage and dirt.
