rating selection jumper is not required.
The figure below shows the terminal definitions for the analog load cell terminal strip. Note that when using four-wire load cells,
jumpers must be placed between the +Excitation and +Sense terminals and between the Excitation and Sense terminals
Note: For the standard four-wire cable: If an increase in load results in a decrease in weight display, reverse the signal wires
