Counting pieces out of a container
1. Place the
FULL
container on the weighing pan and then press the
<TARE>
key to tare the scale (the
>0<
symbol should be appear).
2. Press the
<
☼
>
key to go into piece counting mode.
3. If need be, perform sampling as below;
a. Press the
<
☼
>
key for more than one second until the sampling quantity is seen.
b. Change the sampling quantity using the numerical keys.
c. Remove the sampling quantity of pieces entered above from the weighing container and then
press the
<ENTER>
key to complete sampling and calculation of the APW.
d. The scale starts to count the parts by displaying the number of pieces removed after sampling by
showing a minus sign.
4. Alternatively select the item APW from APW memory (below).
5. Take pieces out of the container until the required quantity shows on the display.
6. The scale displays the number of pieces removed with a minus sign.
7. Press the
<TARE>
key to return the display to zero ready to count the next quantity from the
container.
Press the
<
☼
>
key to go back to normal weighing.
APW optimisation
Sampling with a larger quantity gives more accurate result although the higher quantity is not always
easy to count by hand. APW optimization is strongly recommended for faster counting with higher
sampling quantities for more accurate piece counting, especially when entering APW values into APW
memory.
Follow the procedure below for APW optimisation;
1. First count a small quantity, for example 10 pcs. and do sampling with 10 pcs.
2. Then count on the scale 2 times the initial sampled quantity above. In our example count 20 pcs. on
the scale and apply sampling for 20 pcs.
3. Then count 50 pcs. on the scale and perform sampling with 50 pcs.
4. Then you can count 100 pcs. on the scale and perform sampling with 100 pcs, for much improved
sampling accuracy.
After each APW optimization, piece counting accuracy will increase because of statistically more
accurate APW calculation.
Saving APW to memory after sampling
Up to 500 average piece weights (APW) of different materials can be saved into the APW memory.
1. Press the
<MEM>
key for more than second to enter piece counting memory..
2. Press the
<APW>
key to enter APW memory. The prompt
[ APW: 001 ]
appears.
3. Enter the required APW memory code by using the numerical keys and press
<ENTER>
. The display
indicates the memory code and the old APW value.
4. Press the
<TARE>
key to insert the current APW value into this data field, e.g.
[APW 123: 6.465434]
.
5. Press the
<ENTER>
key to record the APW value into memory.
6. Press the
<ESC>
key to exit piece counting.
Entering the Average Piece Weight numerically into memory
1. Press the
<MEM>
key for more than second to enter piece counting memory..
2. Press the
<APW>
key to enter APW memory. The prompt
[ APW: 001 ]
appears.
3. Enter the required APW memory code by using the numerical keys and press
<ENTER>
. The display
indicates the memory code and the old APW value.e.g.
[APW 123: 6.465434]
.
4. Enter the new APW value by using the numerical keys.
5. Press the
<ENTER>
key to record the APW value into memory.
6. Press the
<ESC>
key to exit piece counting.
Selecting an APW value from memory
1. Press the
<APW>
key in counting mode to enter APW operation. The current APW value
[ APW :
0.012345 ]
appears on the display.
2. Press the
<MEM>
key to enter APW memory. The last used APW memory code appears on the
display as, e.g.
[ APW : 1 ]
.
3. Enter the memory code of the item by using the numerical or
<UP> <DOWN>
keys and press the
