COUNTING
Counting by Sampling
Place the samples on the platter (e.g. 20 pieces weights 0.05 lb as shown above). Press the key to
sample. The QTY window displays SPL. Enter the sample quantity 20, and then press the key to
confirm.
Press the key
to correct or clear the input figure.
The Wt window displays the sample Weight; the APW window displays Average Piece Weight of samples
and the QTY displays the sample Quantity.
APW Enhancement
The APW (Average Piece Weight) enhancement can be activated in the Setup Mode (F5=1). This
enhancement is used to get a more accurate APW. After a sampling is complete, the scale will
automatically re-calculate the APW. However, the added quantity of pieces should be less than the quantity
on the scale. The scale gives a ‘beep’ after every APW enhancement. The function is always available
unless the added quantity of pieces is more than that the quantity on the scale.
For example:
Sampling with 20 pieces
that weight 0.04 lb and an
APW 0.002 lb.
If you add another 19 pieces
to the scale (≤ 20 pcs), a
beep indicates that the APW
is automatically recalculated
to 0.0020115 lb.
If you add another 39 pieces
to the scale (≤ 39 pcs), again,
a beep indicates that the APW
is automatically recalculated to
0.0020208 lb.
