PR/SR balances
5.2 Piece counting – " Count "
With the piece counting application you count parts of approximately equal weight. The piece weight needed for counting is
calculated by the balance after you have loaded a known number of pieces and set this number equal to the reference.
With the reference optimization function "Opt", the piece weight can be recalculated more accurately after increasing the piece
number.
If the piece weight is known, you can also enter its numeric value directly.
In piece counting you have the following functions and information available in the
bottom line of the display:
"Fix n" for calculation of the piece weight from n pieces, n is selectable
"Opt" for improving the counting accuracy by recalculation of the piece
weight
"Set" for setting a reference number or for entry/inquiry of the piece weight
"Unit1" for switching between piece number and weight if you have already
calculated a reference
extended basic functions (see section 4) if activated in the menu.
1. Reference calculation – determination of the piece weight
Depending on the weighing task, the piece weight can be calculated in one of three
different ways:
Reference calculation with preset reference number
Place container in center of weighing pan and tare.
Applications – Piece counting
