The balance type must be preselected at the Coulometer with the <CONFIG> key.
The weight is transferred as a number with up to 6 digits, sign and decimal point. Units
and control characters sent by the balance are not transmitted.
With the aid of a special input unit supplied by the balance manufacturer identifications
and methods can be inputted from the balance in addition to the weight. For this, the ad-
dress of the identifications and method must each be preselected on the input unit.
Balance Method Id1 Id2 Id3
Sartorius METH or 27 ID.1 or 26 ID.2 or 24 C-20 or 23
Mettler (AT) D (Mthd)
C (ID#1) B (ID#2)
A (c20)
If balance and printer are connected at the same Coulometer COM you need the
6.2125.010 and 6.2125.030 Adapters.
If the balance works only with 7 bit and the printer with 8 bit and if they are at the same
Coulometer COM, the balance has to be set to "space parity" and Coulometer/printer to 8
bit, "no parity".
