CHAPTER 4: ADVANCED FEATURES AND OPERATION
4.1 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 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 4-1 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 ZERO key.
2. Press the SAMPLE key. The scale will display “5 0 pcs”. The scale is prompting you to place five
identical items on the platform.
NOTE: If you wish to change the sample number, simply press the SAMPLE key repeatedly
until the desired sample number appears. Available choices are 5, 10, 20, 50, 100, 200, and
500.
3. Place the sample items on the platform all at once. Once the scale stabilizes, the scale will display “5
– pcs”.
4. Press the SAMPLE key to take the sample. If the sample meets the limits shown in Table 4-1, the
scale will now display the number of pieces on the scale. If it does not, the scale briefly displays an
“Lo”, but still allows piece counting. If this occurs, you should use a higher sample amount to achieve
better piece count accuracy.
NOTE: If the scale displays an “Add” message, the unit weight of the items you wish to count or
total sample weight is too light for your scale to process at all.
