Section 9. Troubleshooting
General problem resolution:
Problem:
What to Do or Check:
Weight reading will not repeat or
scale does not return to zero when
weight is removed.
Make sure that the scale platter is not
rubbing or touching the scale cover. Verify
that there is nothing caught in the platform,
under or around the load cell or spider.
Scale overloads early
Verify scale calibration is correct. If
problem persists, recalibrate the scale.
Scale will not come to zero when the
ZERO button is pressed.
Make sure that the scale is becoming
stable (Motion annunciator is off.) After
pressing the zero button, the scale should
zero as soon as it becomes stable.
If problem persists, there may be a
problem with the touch panel or
motherboard.
Weight readings don’t seem to be
correct.
Verify the scale calibration with an
accurate test weight. If the readings are
not correct, recalibrate.
Scale drifts off zero.
Check for air currents and/or vibration
around the scale. If that is the cause, it
may be necessary to set the AZT and nnA
parameters to wider settings to
compensate (see the parameter section.)
Verify that no mechanical restrictions exist,
i.e. platter rubbing, something caught
under or around the load cell.
Bubble level cannot be centered.
Place scale on level surface. If problem
persists, replace the bubble level and
recalibrate.
Scale shuts itself off or will not turn
on.
Check the AO (Auto Off) parameter.
Increase shut off time if necessary.
Battery or transformer may be bad.
See the battery section for testing the
battery and wall transformer.
