System Inaccurate
(continued)
Mounts, Platform or Cart Not Shimmed or Supported Properly to
Provide Equal Load at Each Load Cell:
On MOBILE applications, side pressure on a wheel or tongue can cause inaccurate
readings. Make sure wheels are on a level surface and there is no draw bar pull on
tongue.
On PLATFORM applications, use a large screwdriver or pry bar to pry up on the corners
of the deck. If one of the corners has noticeably less resistance, the deck may require
shimming or adjustment of the leveling screws (if present).
On FEED BIN applications, rock the bin back and forth, and check the mounts for any
movement or play. Insure that each mount has equal pressure and is secured to the slab.
Defective Load Cell:
If you suspect that you have a defective load cell, test them using the procedure on page
11.
Load Cell Up-Side Down:
If one load cell is mounted up-side down, the corner with the upside-down cell would read
negative. Visually check load cells for proper orientation (see below). The load cell should
deflect the same direction as the black arrow on the end of the cell.
NOTE: Each load cell is manufactured so that the cable comes off of the same side of the
cell (see diagram). Decals are also placed on the same side of each load cell.
