Calibrating weigher
To calibrate the weigher, a calibration weight is required. Use a calibration weight that
is nearly as heavy as the maximum empty weight of the weigher/blender.
Calibrate the weigher as follows
1. Empty the weigher completely so the feed computer can determine the zero point.
2. Select
Zero
.
3. Press
Ready
to enter the zero point of the weigher.
Tab page

will appear again.
Zero
shows the number of counts of the
zero point. Place a sufficiently heavy calibration weight in the weigher.
4. Select
Span
.
5. Enter the
Calibration weight
in the screen that appears. Press
Ready
to calibrate
the weigher with this weight.
Tab page
Weighing
will appear again. In
Span
the calibration weight will appear
with the corresponding number of counts.
Setting weigher accuracy
When the weigher has been calibrated, determine weigher accuracy and carry out any
further weigher calibration. The control computer uses the settings below to determine
when a measurement is reliable.
Filter (second)
Setting of the period within which the measured weight must be stable within the limits
of the entered differences (
Weight stable
).
Weight stable
Setting of the value of
Weight stable
(in KG).
Within the
Filter
time the difference between the highest and lowest weight must not
exceed
Weight stable
. If the alarm message ‘weigher not stable’ appears, this value
can be increased.
Counts
Readout of the actual number of counts currently being read on the input.
