Precautions for connecting with the 4-wire configuration
Make sure to do the following when connecting with the 4-wire configuration.
Short-circuit between EXC+ and SEN+, and between EXC- and SEN-.
When using a long a load cell cable, use one with a cross-sectional area that is
as large as possible. Also, use a cable that is as short as possible.

Remark
6-wire
configuration
(recommended)
Less error even if
the length of load cell
cable is long or a thin
load cell cable is used.
Less error even if multiple
load cells are used.
Slightly complicated to wire.
When using a summing box,
it is strongly recommended
wiring be done with the
6-wire configuration.
4-wire
configuration
Easy to wire.
The accuracy of temperature
counting is affected by
resistance of the conductor
wire for the load cell cable.
It is affected by contact
resistance of the connector.
Using a long load cell
cable or multiple load cells
tends to cause error.
