3.0 Adjustments and Calibration
3.1 Mechanical Adjustments
CAUTION
To accommodate minor unevenness, scale feet can be used to adjust scale height up or down a fraction of an inch. Adjust the feet
using the top access foot adjust holes until all feet are contacting the floor equally. No jam nuts are supplied for locking the feet, as
there is a slight decrease in accuracy when jam nuts are tightened. However, if you feel that your application requires you to secure
the feet, we suggest using Teflon
® 1 tape or Loctite ® 2 .
When adjusting scale feet, use care to prevent scale foot from bottoming out against the underside of the
load cell. Also, the foot stem may be damaged by bending or stripping threads if extended beyond the
maximum height adjustment.
When height adjustments are complete, recheck level of the deck with a spirit level. The deck must be level within
1
/

".
3.2 Corner Correction
All assembled RoughDeck scales are delivered with the junction box corner-trimmed. Corner trimming is only
necessary after replacing a load cell.
To calibrate the scale, the output from each load cell must be matched by adjusting the signals with potentiometers
at the junction box—a process known as trimming. For more information on that, see Section 2.5.1.
