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

®

  300.  To  connect  the  balance  to  the  TITRONIC

®

  300,  the  balance  must  have  a  RS-

232-C-interface  and  the  connection  cable  must  be  configured  accordingly.  For  the  following  types  of  balances 
there are already assembled connection cables: 

Balance

 

TZ-Number 

Sartorius (all types with 25 pin RS)  

TZ 3092 

Mettler, AB-S, AG, PG 

TZ 3099 

New Sartorius balances with USB-Interface (via RS-converter) 

TZ 3099 

Precisa XT-Series 

TZ 3183 

Kern with 9-pole RS232 

TZ 3180 

 
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

®

  300.  This  side  of  the 

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

®

  300,  the  data  transmission  parameters  of  the 

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

®

 300 cannot process the balance data 

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

®

 300, you can now test the data transfer of the 

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

®

 300 and the transmitted balance data appear: 

 

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:
