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 there is nothing caught in the platform
under or around the load cell or spider interfering with its
movement.
Scale overloads early.
Make sure all four corner overload stops are properly set,
if present. Take the platter off the scale, invert it and
place it back on the spider. With 1/2 of the scale's
capacity in test weights concentrated over a corner of the
platform, there should be approximately 1/32" of
clearance between the stop and the bottom of the spider.
Check all four corners then recalibrate the scale. If the
problem persists, it is possible that the scale is being
shock-loaded causing the load cell to be shifted.
Scale will not indicate full
capacity or go into
overload.
Make sure that there is nothing caught in the scale under
or around the load cell or spider, which would interfere
with their movement. If not, check the overload stops
using the above procedure.
Scale will not come to zero
when the ZERO button is
pressed.
Make sure that the scale is stable ("MOT" annunciator is
off) when ZERO is pressed. If excessive motion is a
problem, then it may be necessary to activate the latching
print feature (
POd
) or lengthen the filter time (
Avg16
). If
the scale is stable, the scale may be set to the Canadian
Legal for Trade (4% zero bandwidth). An attempt is being
made to zero more than 4% of capacity (see Parameter
Setup section). There may be a problem with the touch-
panel or main board.
Weight readings don't
seem to be correct.
Check the scale's accuracy with a test weight. Recalibrate
if necessary.
Scale drifts off of zero.
Check for air currents and/or vibration around the scale. If
that is the cause, it may be necessary to set the AZT
aperture to a wider setting to compensate (see Parameter
Setup section).
Scale reading is bouncing or
"flighty".
Check for air currents and/or vibration around the scale.
If that is the cause, it may be necessary to set the Digital
Averaging to a higher setting to stabilize the reading (see
Parameter Setup section).
If you are still experiencing a problem with your scale, or if the problem you are having is
not covered in the previous list, please contact your Doran Scales authorized dealer.
