Connection of Analytical Balances

As it often happens that the sample is weighed in on an analytical balance, it makes sense to connect this
balance to the TITRONIC
232-C-interface and the connection cable must be configured accordingly. For the following types of balances
there are already assembled connection cables:
Balance
Sartorius (all types with 25 pin RS)
Mettler, AB-S, AG, PG
New Sartorius balances with USB-Interface (via RS-converter)
Precisa XT-Series
Kern with 9-pole RS232
For all other types of balances it is possible to obtain an already assembled connection cable (on demand). For
this we need detailed information about the RS-232-C-interface of the balance used.
The connection cable is to be connected to the RS-232-C-interface 2 of the TITRONIC
connection cables always consists of a 4-pole mini-plug. The other side of the cable can, depending on the type
of balance, be a 25-pole plug (Sartorius) or a 9-pole plug (Mettler AB-S).
In order to allow the balance data to be sent to the TITRONIC
titrator and the balance must correspond to each other. Additionally, it is necessary to carry out some more
standard settings on the side of the balances:
 The balance is to send the balance data via RS-232-C only by means of a print command.
 The balance is to send the balance data only after the display standstill.
 The balance should never be set to 'automatic sending' and/or 'send continuously'.
 'Handshake' on the balance must be set to 'off', or even 'Software Handshake' or 'Pause'.
 No special characters such as S or St are allowed to be used as prefix in the balance data of the balance
data string. In such a case it might be possible that the TITRONIC
correctly.
After you have connected the balance with the appropriate cable to the TITRONIC® 300 and have adjusted all
settings in the balance software, and possibly in the TITRONIC
balance very easily. Start the one method. Confirm the sample designation. Then, the display asks you:
a) To press the print-button at the balance  Parameters to 'weighted sample automatically'
b) To enter the weighted sample  then the parameters are still set to 'weighted sample manually'
Put an object onto the balance and press the print button. After the standstill of the balance display there will be
beep at the TITRONIC
•
After approx. 5 sec. in the display and the display changes automatically into the measuring display.
•
The weighted sample must again be confirmed with <Enter> or <F1>.

6.1 Balance data editor

Pressing the die <F5/balance symbol > function key will invoke the so-called balance data editor.
A list with the existing balance data will appear:
