Reference Sample Updating
Automatic reference sample updating
optimizes the counting accuracy.
You can activate or de-activate this
function in the menu.
Automatic reference sample updating is
performed when:
– the criterion for the stability parameter
selected in the menu has been met
– the current piece count is less than twice
the original piece count
– the current piece count is less than
100 + the initialization value
– the internally calculated piece count
(such as 17.24 pcs) differs by less than
± 0.3 pcs from the whole number
(17 pcs in this example)
> The abbreviation opt, for “optimizing",
is displayed briefly with the new reference
sample quantity.
Reference Weighing
(Counting with two balances/scales)
Purpose:
Use of a reference balance/scale affords
higher precision in counting large amounts
of parts. The CP balance is used to deter-
mine the reference weight. The following
Sartorius terminals can be used for sample
weighing in conjunction with a reference
balance/scale:
– For QC scales menu code 8 8 2
– For FB/FC/LA/LP series balances/scales,
menu code 8 8 3
– For isi terminals 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 CP balance:
Set menu codes 7 1 2 and 7 2 2
– All data interface parameters
– Baud rate
– Parity
– Number of stop bits
– Handshake mode
Transfer Function in the CP Balance:
– Press the v key
> The reference value is transferred to the
counting balance/scale
Counting Balance/Scale:
$ See the operating instructions of the
balance/scale in question for details
