Scale Calibration
Periodic zero and full calibration ensures that the MGF is weighing correctly. Calibration is also
necessary if a load cell is replaced or if the controller is replaced. Before doing a calibration, you
will need a known weight that can be rested on top of the hopper lid. The known weight must
weigh approximately 4000 grams and you must know exactly how many grams it actually weighs.
This weight in grams will be entered into the MGF. Also be sure of the following:
BE SURE
the material hopper is EMPTY.
BE SURE
the load cell connector is plugged into the side of the controller.
BE SURE
the LOADER material hose is connected to the hopper lid.
Calibration Sequence:
Turn the MGF on. View the Main Menu screen on the LCD window.
