PROBLEM

POSSIBLE SOLUTION

Zero balance out 

of adjustment

The weighing beam must be balanced so the pointer comes to a rest in 

the center of the eye loop (shown in Fig. 9) when both poise weights are 

set at zero (see page 1 for poise weight location). Follow zero adjustment 

instructions on page 5.

Beam does not move freely

Make sure the pointer is not touching the side of the eye loop, impeding its 

range of travel. 

Visually ensure that the linkage is centered and properly aligned. 

Occasionally during shipping, the alignment will become skewed. The 

linkage must be free floating in order for the scale to weigh properly. If the 

scale is slightly tipped to one side, the linkage can be seen by looking up 

underneath the top weigh beam.

Platform rocks excessively

Ensure scale is sitting on a level surface. When you push down on any 

corner of the platform, you should not feel any significant rocking.

Beam does not move at all 

during weighing

Weights are set higher than the person’s actual weight. 

Reset the weights to a lower weight. 

 Make sure steel rod is properly connected and aligned as in Fig. 5

Scale is out of calibration

Recalibrate the scale by placing a known weight on the scale and turning the 

zero adjustment screw until the pointer remains centered within the eye.
