Preparation
To calculate a piece count, the
average weight of one piece must
be known. This average piece
weight can be entered into the
Counting program in one of three
ways:
– The last reference sample
quantity entered is loaded and
displayed when you turn on the
scale. Place the same number of
parts on the scale and initialize
the Counting program;
– With the automatic initialization
parameter on, the scale goes
into the "Counting" mode when
you turn it on and loads the
last average piece weight and
corresponding reference
sample quantity that were entered
or calculated;
– Enter the average piece
weight using the numeric keys
and store it.
Reference Sample Updating
When the updat soft key is
displayed during counting, this
means you can have the average
piece weight updated (while
the piece count is displayed in the
measured value line) provided that
the manual or automatic mode has
been selected in the Setup menu for
reference sample updating.
The updat soft key is displayed
when:
– the scale has reached stability
– the current piece count is less than
double the original piece count
– the current piece count is less
than 100
– the internally calculated piece
count (e.g., 17.24 pcs) differs from
the nearest whole number (here:
17 pcs) by less than ±0.3
Reference sample updating can be
repeated several times with an
approximately doubled piece count.
