Troubleshooting
Before contacting service personnel, refer to the following instructions to check and to correct
any failures for incorrect weight measurements.
The accuracy of the 402KL scale when calibrated at the factory is within +/- 0.1kg or ¼ pound.
For the most accurate weight measurement, use the scale on a hard level surface and stand in
the center of the platform. If the error seems excessive, check the following:

Possible Cause Corrective Action
The balance ball must be balanced such that the
pointer comes to rest in the center of the trig-loop
when both poise weights are set at "0" value.
Ensure that the upper and lower poise weights
are firmly against the shoulder of the beam.
Adjust the balance ball screw by turning the
screw at the left end of the bar until balanced.
Check if the pointer is touching the side of the trig
loop in its range of travel. Realignment of the
beam may be necessary if it is touching.
Ensure that the upper and lower poise weights
are firmly against the shoulder of the beam.
Adjust the balance ball screw by turning the
screw at the left end of the bar.
Contact technical support at 1(800) 638-3722
Reset the weights to a lower weight.
Ensure the steel rod is connected properly, refer
to "Assembly Instructions" on page 5.
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 ¾" 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
one-quarter pound per 100 pounds.
