5.10 EPC operating mode
When it is configured for the piece counter operating mode (see par. 5.9
on page 1-46), the terminal also provides the following functions:
✔
display of the number of pieces, average unitary weight (called AUW
from now on) and weight;
✔
display of the number of pieces, average unitary weight (called AUW
from now on) and weight;
✔
automatic calculation of the number of pieces.
5.10.1 AUW acquisition
The average unitary weight is a fundamental data item since it allows the
pieces to be calculated correctly. It is therefore very important to take
care when it is acquired as the more accurate it is, the more precise will
piece counting be.
The average unitary weight can be entered in two ways:
✔
it can be acquired from the scale by sampling a defined number of
pieces;
✔
it can be transmitted via serial link by a computer, using the remote
controls (consult par. 9.4 on page 1-69).
If the AUW is acquired, proceed in the following way:
✔
press : the display will show the number of samples and the first
weight for calculating the AUW will be acquired at the same time;
press the key again to display the number of samples that can
be selected from a fixed table. Select the number of samples that will
be successively loaded.
✔
The terminal waits 10 seconds before loading or unloading the pieces
to or from the scale;
✔
the terminal checks the stability of the weight and calculates the
AUW. The message WAIT appears during the phase when the
stability of the weight is checked, which terminates by calculating the
average unitary weight. Samples can be loaded and unloaded on and
from the scale during the time waited for the stable weight condition.
