PREACT definition - A preact is the amount of material in free fall.
For example: You would like 1000 lbs of material added to a scale but when the
supply valve closes you always end up with a final weight that is 120 lbs over the
desired amount.
To correct this, set a preact of 120 lbs. This causes the setpoint controlling the
material to stop sooner and allows the material in free fall to be accounted for in the
final weight.
In Discharge or Negative fill applications using manual preact, the preact weight will
typically be entered as a negative value.
