**With both the “unit weight” and “Quantity” displays showing zero, pressing either the [UNIT W.T.]
key to get unit weight, is the next sample you place is more than 10% of the last sampling or less
than the last sampling present, the scale automatically recalibrates the unit weight. You can set this
function on/off in “F2 ARG”.
**If the weight and count is known, the scale will re-calculate the weight according to the count
shown in the “Quantity” displays when you press the [UNIT W.T].
