5. Extend the weigher arm out until it is perpendicular to the machine’s
chassis. (Ensure no weight is hanging on the arm.)

the Offset value. (Now both Offset value and Input should be equal.)
7. Calibrate the weigher Full Scale value by following the appropriate
procedure below:
Weigher Calibration When Using Collection Bottles
a) Suspend a calibrated 1000 gram weight from the center of the
bottle area by hanging the weight between the weigher arm fingers
using string or a rubber band of minimal weight and thickness.
Place the string or rubber band over the weigher arm fingers so
they are centered within the calibration notches. (See Figure 4-4
below.) The string or rubber band thickness should be small enough
to allow it to center within the calibration notches, but strong
enough to securely hold the weight.
