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.
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
Z
AT 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.
Scale shuts itself off or will not turn
on.
Press the ZERO button to turn on the
indicator.
The transformer may be bad or the power
connector at the rear of the scale may
have an intermittent connection. Check
the power connector at the rear of the
scale.
