Parts Counting - KERN PFB 120-3A Operating Manual

9.2 Parts counting

Before the balance can count parts, it must know the average part weight (i.e.
reference). Proceed by putting on a certain number of the parts to be counted. The
balance determines the total weight and divides it by the number of parts, the so-
called reference quantity. Counting is then carried out on the basis of the calculated
average piece weight.
As a rule:
The higher the reference quantity the higher the counting exactness.
Set reference
 Press the PCS key, the current reference quantity (e.g. 10) and the indicator Pcs
are displayed.
 Press the MODE key to set the desired reference quantity (i.e. 100), selectable
SP 10, SP 20, SP 50, SP 100, SP 200.
 Place as many items to be counted (such as 100 items) as demanded by the set
reference quantity and confirm by ZERO key. The weighing scales calculate the
reference weight. The current quantity (such as 100 items) will be displayed.
 Remove reference weight. The balance is from now in parts counting mode
counting all units on the weighing plate.
Switching over between quantity and weight display
