It will be observed that the MC12 in the prompt line asks for the weight, and the value shown on
the balance must be entered, e.g. 8.25: <8>+<.>+<2>+<5>+.
The filling may begin by pressing +.
8.3 Calibration of grams with balance
A MC12 programmed to fill a quantity measured in grams, should be calibrated by means of a
balance.
The parameters already entered may be used for a trial, where the 8.5 ml equals 8.5 grams. i.e.
Specific gravity is 1.0000 g/ml
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 run a few fillings before the calibration is made. After these
fillings, set F9, reset F8: and F11:
Keep the container under the filling nozzle and press +. The filler makes ONE trial
filling, and the display now shows the following:
CALIBRATION 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 12 – Calibration of grams with balances
It can be observed that the MC12 in the prompt line asks for the weight, and the value shown on
the balance must be entered, e.g. 8.25: <8>+<.>+<2>+<5>+, If grams is selected as
volume format in function 72, the calibration will now be completed.
The filling may begin by pressing +
