As the surroundings of the DF32 may vary from time to time and as pump head and products have
small tolerances, it is necessary to calibrate the filler when it is started.
If the quantity has been entered as volume in ml, a measuring cylinder or a balance may be used as a
control and measuring unit. The balance will always be the more accurate, especially for small
quantities.
The calibration in DF32 is made as following.
This re-calibration can be carried out simultaneously with the fills.
! The DF32 should always be re-calibrated after changing any of the pump parameters:
That is: Volume, Velocity, Acceleration or Reversing!
8.1 Volume calibr ation with measurin g cylinder
IF A VOLUME HAS BEEN ENTERED IN FUNCTION 1, AND A COMPLETED FILL IS MEASURED
IN A MEASURING CYLINDER,
THE SPECIFIC GRAVITY IN FUNCTION 9 MUST ALWAYS BE SET AT THE VALUE 1.0.
The parameters already entered may be used for a trial.
Prepare the measuring cylinder and make sure that the tubes are completely filled, up to and
including the filling needle.
It is recommended to let the filler complete a few fills before the calibration is carried out.
Keep the measuring cylinder below the filling needle and press <calib>+<GO> to complete a single fill
and DF32 will now ask the dispensed volume showing the following display:
CALIB. WEIGHT: 0.0000_
F 1: VOLUME (ml): 50.0
Fig. 8.1
In the prompt line, DF32 prompts for the weight. THE WEIGHT MUST BE ENTERED, i.e. 48.5:
<4>+<8>+<.>+<5>+<ENT>.
DF32 has now automatically adjusted from 48.5 ml to 50.0 ml.
Function 8 should now be reset, and the filling may be started by pressing <disp.>+<GO>.

8.2 Volume calibr ation with balance
IF A VOLUME HAS BEEN ENTERED IN FUNCTION 1, AND A COMPLETED FILL IS MEASURED
WITH A BALANCE,
THE SPECIFIC GRAVITY OF THE LIQUID IN QUESTION IS TO BE ENTERED IN FUNCTION 9.
The parameters already entered may be used for a trial.
Prepare the balance by tarring the container and make sure that the tubes are completely filled, up to
and including the filling needle.
It is recommended to let the filler complete a few fills before the calibration is carried out.
Keep the tarred container below the filling needle and complete a single fill by pressing
<calib>+<GO> and DF32 will now ask for the completed volume showing the following display:
CALIB. WEIGHT: 0.0000_
F 1: VOLUME (ml): 50.0
Fig. 8.2
In the prompt line, DF32 asks the weight, and the WEIGHT of the trial fill in question must be entered,
i.e. 46.8: <4>+< 6>+<.>+<8>+<ENT>
DF32 has now automatically adjusted from 46.8 g to 50.0 ml.
Function 8 should now be reset, and the filling may be started by pressing <disp.>+<GO>.
8.3 Re-calibration
During production it may be necessary to recalibrate the volume dispensed by the filler to compensate
for changes in the environment e.g. the liquid level of the feed vessel will sink. This re-calibration may
be carried out without stopping the filling.
IT IS IMPORTANT TO USE THE SAME MEASURING METHOD FOR THE RECALIBRATION AS
USED FOR THE INITIAL CAL IBRATION.
Draw off a filled sample and measure it. Subsequently, the procedure is the same as used when
starting the filling series.
DF32 will now automatically adjust the subsequent fills.

In addition to registering the filling series, DF32 also registers when and from which value
recalibrations were carried out.
If the print-out of the current parameters is left in the printer till the status print-out has been made,
this will give a full production documentation which might look like the one shown overleaf.
