4.2.2 Standard Load Cell Connection

The load cell wiring should be made carefully before energizing to avoid damages to the weight indicator and
the load cells. The input resistance of the load

cells that you want to connect should be more than 58 Ω.

The sense pins of the instrument should be connected. In 4-wire installations the sense and excitation pins with
the same polarity should be short circuited at the connector side.
