The near zero signal is used for
discharge completion confirmation
as in the case of feed weighing.
GROSS for high/low limit comparison, and NET for final weight,
before-final-weight,and near zero comparisons.
(In discharge weighing, NET is compared negatively.)
Materials are fed until the HI limit signal is output.
