e material weight inside the weighing hopper exceeds the target weight-slow-input weight, the controller orders the motor to work in slow speed, the belt material-input mechanism continues to fill into the weighing hopper slowly, when the material weight inside the weighing hopper exceeds the target weight-advanced weight, the motor stops driving the belt material-input mechanism, the controller displays the actual weight in 0.5 seconds. Then the clamping-mechanism will check whether theres sign
