Off-center Error
Checking the Off-center Error
– Center the test weight (see „Service Specifications,“ page 53-54) on the
weighing pan/load plate (Pos. 1) and zero the balance/scale by pressing t.
The readout shows 0.0g (depending on model and settings).
– Place the test weight in Positions 2, 3, 4 and 5 in turn.
– The absolute value displayed for each position must lie within the tolerance
limits listed in the service specifications.
– If the off-center loading error in one of these positions is greater than the
value given in the service specifications, adjust the off-center loading error to
the greatest positive deviation (see „Adjusting the Off-center Loading Error“
below).
Adjusting the Off-center Error
– Open the balance/scale (see page 48).
– Use a 7 mm open-ended wrench to remove the two fastening screws from the
pan support and remove the pan support.
– The strain-gauge load receptor is now accessible.
– The off-center load error is adjusted by filing on a thin part. File the thin part
that corresponds to the greatest error.
Note: Only minor deviations can be adjusted. If the strain-gauge load receptor
is visibly bent, the error cannot be adjusted.
– Replace the pan support on the strain-gauge load receptor and replace the
upper housing, shock absorber and weighing pan/load plate.
– Check the off-center loading error and perform adjustment again if necessary.
