4-Wire Connection
The minimum connectivity requirements are the connection of four wires (i.e. Exci and
– along with and –). Internally the
instrument
has a precision analogue switch that
connects the Sense + and
– lines directly to the Exci and – lines when 4-wire mode is
selected.
A 4-wire connection is only suitable for short cable runs. Where long cable lengths are
needed, a 6-wire extension is required to maintain accuracy.
The BUILD:CABLE option must be set to
4
to allow for 4-wire connection. Refer to
page 33.

6-Wire Connection
The excitation and signal lines are connected the same as for a 4-wire installation. The extra
two wires (Sense + and
–) should be connected to the Exci and – lines as close as
possible to the load cell itself. Typically these connections are made in a load cell termination
box.
The BUILD:CABLE option must be set to
6
(the default) to allow for 6-wire connection. Refer to
page 33.
