He should have ten balance-beams (tulā) made, increasing in length above six aṅgulas by increments of eight aṅgulas; and (corresponding) iron-weight sets increasing above one pala by increments of one pala; or else a weighing device with suspension from both sides.
Different load ranges require different beam lengths and counterweights; standardized sets improve accuracy and reduce scope for dispute.
