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 forks and is accessed by pressing the UNITS 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 scale 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.
1. Press the UNITS key until “PCS” is indicated on the display. If a previous sample
has not been taken, the scale will display “10 0”. If a previous sample has been
taken, the scale will display the current number of pieces on the platform.
2. If the items you will be counting require a container or pallet, you must first tare
the container or pallet off by pressing the TARE key.
3. If the screen does not show “10 0”, press the TARE key once. The scale is
prompting you to place ten identical items on the scale’s forks.
NOTE: If you wish to change the sample number, simply press the NET/GROSS
key repeatedly until the desired sample number appears. Available choices are 5,
10, 25, 50 and 100.
4. Place the sample items on the scale’s forks all at once and allow the weight
indication to stabilize. Once this is done, the zero indicated after the sample
number will change to a “–“. For example, “10 –“.
5. Press the NET/GROSS key to take the sample. If the sample size is large
enough, the scale now displays the number of pieces on the forks. If it does not,
the scale briefly displays “Add” and automatically increments the sample size.
Repeat Step #4 with the new sample size.
NOTE: If the scale continues to display “Add” even after sampling 100 pieces, the
unit weight of the items you wish to count is too light for your scale to process
accurately.
6. To exit the piece count mode, press the UNITS key. The APW will remain in
scale memory until you repeat Steps # 2 or #3.
