Counting
Menu code:
2 1 4
Display symbol:
Z
Purpose
With the Counting program you can
determine the number of parts that
each have approximately equal weight.
To do this, a known number of parts
(the reference sample quantity) is
weighed first, and the individual piece
weight (reference weight) is calculated
from this result. Thus the number
of parts subsequently placed on the
balance can be determined from
their weight.
Reference Sample Updating
Automatic reference sample updating
optimizes the counting accuracy.
You can activate or deactivate this
function in the Setup menu.
When this function is active, automatic
reference sample updating is performed
when the selected stability criterion has
been met.
> The abbreviation
opt
, for “optimizing,"
is displayed briefly with the new
reference sample quantity.
Reference Balance/Scale
(Counting with two balances/scales)
Purpose:
Use of a reference balance/scale affords
higher precision in counting large
amounts of parts. The LE balance is
used to determine the reference weight.
The following weighing instruments or
terminals can be used for sample
weighing in conjunction with a refer-
ence balance/scale:
– For a QC scale: set menu code
8 8 2
– For an FB/FC/LA/LP balance/scale:
set menu code
8 8 3
– For an isi terminal:
set menu code
8 8 4
§
Please order the required connecting
cables directly from Sartorius.
The following settings must have the
same configurations in both
balances/scales:
– Counting program
– Weight units
– Settings in the LE balance:
Menu codes

and
7 2 2
– All data interface parameters:
– Baud rate
– Parity
– Number of stop bits
– Handshake mode
Transferring the Reference Value from
the LE Reference Balance:
– Press the
