OPERATION

Parts Counting

Parts Counting is

enabled only

when the Parts Counting Function is selected in the

Setup menu. Refer to page 40. In the parts counting mode, the balance displays the
quantity of parts you place on the platform. Since the balance determines the quantity
based on the average weight of a single part, all parts must be reasonably uniform in
weight. The accuracy of parts counting results is determined by the error level entered
in PC Err of the Setup Options submenu. Refer to page 51. The default setting for
PC Err is off.

You can continue to use the balance to measure quantities as long as the
samples to be measured are of the same weight.
