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:Equation:

Equation:

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 Signal + (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.
