9.4.1 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 preset number of parts to be used as a sample.
These values are 10, 25, 50 or 100 items.
Steps:
• Press [Mode] to show parts counting, “PARTS” will be displayed
• Enter parts counting by pressing [Enter]
• Press the [Up] or [Down] key to select the sample size, “REF QTY”,
10, 25, 50, 100, etc., then press [Enter] to confirm
• When “LOAD XX Pcs” is shown place XX number of items on the pan
and press [Enter] 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. A message “PARTS” will be prompted on the top
of the display to indicate that the balance is in the parts counting mode
• Remove the sample and display will show “0 Pcs”.
• Place an unknown quantity 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 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 (weight of each piece
should be > 1d)
• To return to normal weighing, press [Esc]
