For many years, a tablet or capsule checkweigher was viewed primarily as a piece of production equipment. Product went in. A weight was measured. Acceptable and unacceptable units were separated. A batch report might then be printed or exported.

Those records may subsequently support investigations, process decisions, batch recovery, validation activity or quality review.

This changes what manufacturers should expect from the equipment — and what they should ask of the supplier.
