8.4 Recalibration
During the production it may be necessary to recalibrate the volume dispensed by the filler, as
for example the liquid level of the suction vessel will sink. This recalibration can be made without
stopping the fillings.
IT IS IMPORTANT TO USE THE SAME MEASURING METHOD FOR THE RECALIBRATION
AS USED FOR THE INITIAL CALIBRATION.
Draw off a filling sample and measure it.
Press +, and the display will show the following:
RECALIBRATION WEIGHT:
F 1: 8.50 ml
F 3: 400 rpm
F 5: 1 REV. 0.0000 X1
F 2: 3.2 TUBE
F 4: 35 ACC
F 6: 100 fills
Figure 13 – Recalibration
Enter the measured value, e.g. 8.47: <8>+<.>+<4>+<7>+, and MC12 will now
automatically correct the filler from 8.47 to 8.5 as asked.
MC12 uses the specific gravity entered in F9.
8.5 Calibration in parallel mode
When MC12 is working with several pumps in parallel mode the system is controlled from Drive
0.
When calibration or recalibration is needed, at first the MC12 will ask for the actual drive and
when this information has been keyed in, the procedure will be the same as described above.
8.6 Calibration in serial mode
When MC12 is working with several pumps in serial mode the system is controlled from Drive 0.
When calibration or recalibration is needed, the MC12 will consider all drives as being one
single filler and the procedure will be the same as described above.
