CHIEVED CCURACY
Achieved accuracy is insufficient to allow an enhancement to occur with at
least 5 additional pieces: The controller prompts you to Add xx parts,
where "xx" is the number of additional parts required to allow either
enhancements to be achieved, or the number required to achieve the
required accuracy, whichever is less. Add the specified number of parts
and press [ENTER], or add even more parts, key in the TOTAL number of
parts on the scale, and press [ENTER].
The controller will show the current quantity on the numeric display and
the message Enhn# xx on the alpha display. "Xx" is the maximum number
of parts that may be on the scale in order for an enhancement to occur.
You can then add more parts, up to the number shown.
As soon as motion ceases, if the quantity displayed is more than the
original sampled amount and less than the displayed maximum enhance
amount, the piece weight will be re-calculated. Then the achieved
accuracy will be re-evaluated. If the required accuracy still has not been
achieved, another enhancement will be required and this step will be
repeated with a larger maximum enhance amount. If you add more parts
than specified, Code 53 Accy >Req'd is displayed, indicating that the
required accuracy has not been achieved and counting may not continue.

CHIEVED CCURACY
Achieved accuracy is insufficient to allow an enhancement to occur: The
message Can't Enhnc is displayed briefly. This will not normally occur
unless the sampled number of parts was very large and / or the piece
weight was relatively small. Sampled amount is sufficient to allow
enhancements: The maximum number of parts which can be counted and
allow an enhancement to occur is displayed briefly and the quantity is then
displayed.
In order for a given accuracy to be achieved, the weight of the sampled
parts must meet or exceed a specific minimum. Table 5-2 shows the
required sample weight for various accuracy requirements on a variety of
platform capacities.
Table 5-2 s calculated for the filter selection of 8 seconds. It also is based
on a load cell full scale input of 2 mV/V.
If a 1 mV/V full scale cell is used, all minimum weight requirements
If a 3 mV/V cell is used, the value should be 2/3 the value shown.
