Trimming Procedure
7
7. Allow the scale to return to zero each time to check for friction or other
mechanical problems.
8. Select the load cell with the lowest value as the reference load cell. This load cell
will not be trimmed.
9. Place the same test load over one of the other load cells.
10.Use the corresponding potentiometer to trim the load cell equal to the reference
load cell.
11.Repeat Steps 9 and 10 until all remaining load cells have been trimmed.
12.Once trimming is complete, check all loads cells again for repeatability. If
necessary, repeat Steps 4 through 11.
13.Pull excess cable out of the enclosure.
14.Tighten the cord grip assemblies with a wrench. To be watertight, each cord grip
must be tightened so the rubber sleeve begins to protrude from the hub.
15.Plug unused hubs to prevent moisture entry.
16.Place the supplied desiccant filter it in the junction box.
17.Replace the cover and tighten the screws in an alternating pattern to be certain
the gasket is compressed equally in all locations.
See the Electronic Replacement Parts and Components catalog to
order extra hole plugs if needed for Step 15.
Inspect the desiccant during normal service and change the
desiccant as needed.
