Determining the Resistance for Adjustment of the Off-center Load

Determining Resistance Values

-   Place the test weight on each load cell in turn and write down each displayed 

value.

-  Using the lowest displayed value as the basis, calculated the resistance values 

for the other load cells in accordance with the following equation:

Equation:    R  =  R(0) x G(D) / G(T)

R 

=  required resistance (in ohms) 

R(0)  =  Initial resistance in the load cell being adjusted (in ohms), (if not specified 

in the specification sheet) measured between (OUT_POS, positive 
measuring voltage) and Signal - (OUT_NEG, negative measuring voltage).  
 

G(D)  =  Difference between lowest off-center loading error (from reference load 

cell) and the off-center load value displayed for the weigh cell (in kg).   

G(T) =  Test weight applied (in kg)  

-   Solder the required resistor into the bridge of the load cell being adjusted.
-  Then perform calibration/adjustment again.
