8. CALIBRATION
As the surroundings may vary from time to time and as tubes and products have small tolerance
deviations, 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 control and measuring unit. The balance will always be most accurate, especially when the
quantities are small.
8.1 Calibration with measuring cylinder
NB. 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 nozzle.
It is recommended to let the filler complete a few fillings before the calibration is made.
After these fillings, set F9, reset F8: and F11:
Keep the measuring cylinder below the filling nozzle and press
complete ONE trial filling, and the display will now show the following:
CALIBRATION WEIGHT:
F 1: 8.50 ml
F 3: 400 rpm
F 5: 1 REV.

F 2: 3.2 TUBE
F 4: 35 ACC
F 6: 100 fills

It will be observed that the MC12 in the prompt line asks for the weight.
THE WEIGHT MUST BE ENTERED, e.g. 8.05: <8>+<.>+<0>+<5>+
The filling may begin by pressing
8.2 Calibration with balances
NB. The parameters already entered may be used for a trial
Reset the balance with the container (bottle) to be used for the trial filling and make sure that the
tubes are completely filled, up to and including the filling nozzle.
It is recommended to let the filler complete a few fillings before the calibration is made. After
these fillings, set F9, reset F8: and F11:
Keep the container below the filling nozzle and press
