3. Each MM27BC meter has the following
internal parameters:
Bias-Factor:
One value that is used to fix the meas-
ured MM27BC bias.
Sub-Software:
This number represents the algorithm
used by the MM27BC to compute
the yield. It is set when installing the
MM27BC and must remain constant.
(E.g. low line.)
Optical channel:
The milk channel and optical field must
stay the same as it was at the time for
calibration.
If by some malfunction the parameters
above have been changed, these para-
meters must be restored to the original
values. If not, the meters should be recali-
brated with milk.
Use VPR100 or PSION to read the para-
meters.
Check of internal parameters:
The meters Optical channel must be
checked. The milk channel characteristics
and optical field must stay the same as it
was at the time for calibration.
The test probe is simulating a milk flow.
The MM27BC flow reading is compared
to the original reading obtained during the
installation test. If the obtained value is the
same, then the optical field and milk channel
characteristics have all stayed the same and
the MM27BC measures as during the instal-
lation test.
For this test, a probe and the remote con-
trol unit (Psion/VPR100) are required. The
probe should be cleaned before usage and
as the probes are not perfectly identical; the
same probe should be used during the rou-
tine testing. The probe belongs to the milk-
