• Cable For interconnections of the 818 IC Pump with
non-Metrohm units, only a shielded data cable
(e.g. Metrohm D.104.0201) may be used. The
cable shielding must be faultlessly earthed at
both units (pay attention to current loops;
always use star-head earthing). Only
connectors with adequate shielding may be
used (e.g. Metrohm K.210.0001 with
K.210.9004).
• Cable length max. ca. 15 m
