5.2 Balance
Problem Cause Remedy
The sample size is
not or not correctly
received. The parameters of the
RS-232 interface are
wrongly set. Correct the RS-232 parameters (see page
39ff). They have to match with those of the
balance.
The connection cable is
unsuitable. Use the RS-232 cable of the balance manufac-
turer or ask for the corresponding cable from
Metrohm.
