However, the overload protection may be triggered even with smaller forces.
Load holders must generally be rigid and torsion-resistant. Atest is recommended because there may be unwanted
reactions on the control loop. The influences of drafts and the instructions for analytical weighing must be considered.

Weigh Cell Operating Instructions 19
System Settings
7.2 Synchronization
During data communication between weigh cell and
computer, messages consisting of ASCII characters are
transmitted via the interface. For error-free data ex-
change, parameters for baud rate, parity, handshake
mode, and character format must be identical for both
units.
Settings can be changed in the menu to customize the
weigh cell.
7.3 Handshake
The weigh cell interface SBI (Sartorius Balance
Interface) has transmit and receive buffers. Different
handshake modes can be set in the weigh cell menu:
— Hardware handshake (CTS/RTS)
— Software handshake (XON, XOFF)
— No handshake
7.3.1 Hardware Handshake
When hardware handshake is configured on a 4-wire
interface, one more character can be transmitted after
CTS.
7.3.2 Software Handshake
The software handshake is controlled via XON and
XOFF. When a device is switched on, XON must be
transmitted to enable any connected device to
communicate.
7.4 Data Output by Print
Command
The print command can be triggered by pressing a key
(YRD01) or via a software command (Esc P).
Optional Power Supply
If the power supply is established with anything other
than the supplied power supply unit:
t NOTICE Risk of
damage to the device
due to the use of an
unsuitable power
supply unit. The
power supply must be
connected in
accordance with the
regulations applicable
in your country.

7.6 Automatic Data Output
In “Automatic Printout” mode, data is output to the data
interface without an extra print command.
You can have synchronized data output automatically at
defined display update intervals, with orwithout weigh
cell stability.The time for an interval depends on the
setting under “Ambient conditions” (code 1. 1. 1. x) and
“Auto output cycle” (code 3. 1. 3. x).
If the automatic data output is activated in the menu, it
starts immediately after the balance is turned on. In the
setup, you can also specify whether the automatic data
output can be stopped and started with a “Print com-
mand” (key or via interface).
7.7 Adjustment
Procedure
t Perform adjustment functions:
— Via control commands with Sartorius
configuration software CAS Suite installed on a
computer (see Chapter “8.6 “Calibration,
Adjustment” Function via Interface RS232
