4. Stand over or hang on each load cell and observe increase in weight reading on the
indicator (displayed weight will not be correct).
5. Disconnect load cell and repeats steps 3 through 6 for each load cell.
6. After all load cells are checked, compare the readings. If one cell is substantially
different than the others, it is bad.
NOTE: Be sure to check each load cell to insure there are not two bad cells.
Using a Multimeter
If an operational indicator or junction box is not available, load cells can be tested using a
multimeter.
NOTE: This method is not fool-proof. A load cell may pass this test and still have a
problem. For best results, test load cells using a working indicator.
1. Identify the load cell type and use the chart on page 12 to determine the resistance
values between the wires on the load cell.
2. Using an ohm meter, measure the resistance between leads on the load cell.
3. Replace the load cell if it measures more than 15% above or below the value listed in
the chart on page 12.
NOTE: Bad load cells will typically show no reading or double the correct value.
