Troubleshooting Guide

INCORRECT WEIGHT
The accuracy of the 402KLWA scale when calibrated at the factory is within plus or minus 0.1kg or ¼ pound. This
means that two properly calibrated scales can vary 0.1kg or ¼ pound from each other and still be calibrated
correctly. For the most accurate weight, use the scale on a hard level surface and stand in the center of the
platform with the weight distributed as evenly as possible. If the error seems excessive, check the following:
1. Zero Balance of the Beam
The beam must be balanced so the pointer comes to rest in the center of the trig-loop when both poises are set
at zero. Make certain that the large poise is firmly against the shoulder of the beam. Adjust the balance by
turning the screw at the left end of the beam.
2. Beam Does Not Move Freely
Check if the beam pointer is touching the side of the trig-loop in its range of travel. Contact Customer Service
Support at one of the numbers listed above for instruction on realigning the beam.
3. Platform Rocks Excessively or Touches Base at Any Corner
When you push down at any corner of the platform you should not feel any significant rocking. If you do,
please contact Customer Service Support at one of the numbers listed above on leveling the platform.
4. Beam Does Not Move at All during Weighing Process
This may be caused by the poises being set to a higher weight than the person's actual weight. Reset the
weights to a lower weight. An improperly connected Steelyard Rod (the rod that runs inside the pillar) or a
disconnected rod which can occur if the scale is transported may also be the cause. See Figure 2.
5. Scale Out of Calibration
This can happen if an adjustment is jolted out of place during transit or by wear in the notches in the beam
after a long period of use. Lifting the large poise over the notches during movement will preserve the accuracy
of the scale and lengthen the life of the beam. The accuracy should be determined with accurate test weights
or the scale can be compared to a scale known to accurate, such as a commercial scale with a Weights &
Measures sticker affixed. The scale can be recalibrated by loosening the lock screw at the end of the long lever
in the bottom of the base with a 5/16" hexagon socket wrench and moving it outward (longer) in the elongated
slot to decrease the indicated weight or inward (shorter) to increase the indicated weight. One sixteenth inch
movement of the screw will change the indicated weight by approximately 0.1kg per 45.35 kgs or ¼ pound per
100 pounds.
