TROUBLESHOOTING
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 450KL 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:

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 large and small 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 large and small 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.
