3.3.5 PIECE COUNTING
This mode is used to indicate the number of pieces of an item you have placed on the
scale’s platform and is accessed by pressing the SAMPLE soft key. To ensure accuracy, the
parts you are counting must be consistent in weight.
The scale uses the sampling method to determine the average piece weight (APW) of the
items you wish to count. When sampling items, always count the parts in your hand and
place them on the platform all at once. If the APW of the items is too light or the total weight
of the sample is too light, accuracy cannot be guaranteed. You will get an error message, but
piece counting will still be allowed. Consult Table 3-2 for minimum piece weights and sample
weights.
1. If the items you will be counting require a container, you must first tare the container
off by pressing the TARE soft key. The scale switches to NET mode and sets the displayed
weight to zero.
NOTE:
Enabling the Auto Tare feature in the Supervisor Menu (Chapter 5) can elimi-
nate this step.
2. Press the SAMPLE soft key. The scale will display “Add 10 pcs to the platter then
press the ENT key”. The scale is prompting you to place ten identical items on the
platform.
NOTE:
If you wish to change the sample number, simply choose a displayed soft key
selection. Available choices are 5, 10, 25, 50 and 100. If you have a non-standard
sample amount, press the Key-in soft key to enter the sample number.
3. Place the sample items on the platform all at once and press the ENT key to take the
sample. If the sample meets the limits shown in Table 3-2, the scale will now display
the number of pieces on the scale. If it does not, the scale briefly displays an error
message, but still allows piece counting. If this occurs, you should use a higher sam-
ple amount to achieve better piece count accuracy. Please see Appendix C for an
explanation of the error messages.
NOTE 1:
You can eliminate the need to press the ENT key by enabling the Auto
Sampling feature in the Supervisor Menu (Chapter 5).
NOTE 2:
You can program the scale to automatically switch from the local scale to
the remote scale (if equipped) by enabling the Auto Switch Channel feature in the
Supervisor Menu (Chapter 5). The scale will automatically switch channels after a
successfully sample has been made.
NOTE 3:
If the scale displays a “Low Resolution” message, the unit weight of the
items you wish to count is too light for your scale to process at all.
3.3.6 CLEARING THE PIECE COUNT
1. To clear the piece count, either press the CLR key to erase the sample or press the
SAMPLE soft key to take a new sample.
