5.3. Load Cell Connection

The load cell wiring should be made carefully before energizing to avoid damages to the amplifier and the load

cells. The input resistance of the load cells that you want to connect should be ≥ 50 Ω (ohms).

In case of using a load cell / scale with 4 wire cable, you have to short-circuit (bridge) the pins 1 & 2 and 6 & 7.

Remark: Please don’t shorten the 4 wire cable of a load cell, as the cable is part of the factory calibration

(signal & temperature compensation).
