10.4.1 Parts Counting
This allows the user to weigh a sample of parts to compute an average unit weight and then
determine the number of items being weighed by dividing the net weight by the unit weight
value. The result is always a whole number of parts.
The balance will have a pre-set number of parts to be used as a sample. These values are
10, 25, 50 or 100 items.
Press
[Mode] and cycle through the available options until the “ Parts ” symbol is displayed.
Now enter parts counting mode by pressing [Setup] .
Press the
[Up] or [Down] key to select the sample size  where XX=10, 25,
50, 100) then press [Setup] to confirm.
When
 is shown, place XX number of items on the pan and press [Setup] to
compute the average piece weight. Display will indicate the total weight in the last selected
unit and then show “XX
PCS
” sounding a beep.
Remove the sample and display will show

Place an unknown quantity of parts on the pan. The balance will then compute the number
of parts based on the average piece weight. The display will show the result in number of
pieces. This will be an integer value in the format “XX
PCS ”.
To count another item press [Mode] and continue as before.
Checks will be made to determine that the weight of the reference parts is large enough for
reasonably accurate counting (the weight of each piece must be > 1 division of the balance).
To return to normal weighing, press the
[Esc] key.
10.4.2 Percentage Weighing
Percent weighing will be done by defining a certain weight to be 100%. The weight to be
used can either be entered by the user or taken from a sample
Press
[Mode] and then the [Up] or [Down] key until the “
Percent
” symbol is displayed. Now
enter percent weighing mode by pressing [Setup] .
Display will show
 sample method) or  (manual weight method).
Press the [Up] or [Down] keys to toggle between the two methods and press [Setup] to
select the desired method.
10.4.2.1 Sample method:
When  is displayed, press [Setup] .
When  followed by  is shown, carefully add the sample to the pan. Now press
[Setup] to set this weight to be 100%. The display will show  and the sample
weight in the last selected unit. After a short pause  will be displayed.
