Section 8. 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 overload stops are properly set.
Take the platter off the platform, 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. Review the
cautions in section 1.
Scale will not indicate full
capacity or go into overload.
Make sure that there is nothing caught in the
platform 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 (Av A1).
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 Section 4).
There may be a problem with the touch-panel or
main board,
