NOTE: Scale is delivered pre-calibrated.
Calibration can only be done in metric
system weight.
there is no need to calibrate the scale unless you feel
it has become inaccurate. you must use precision test
weights to calibrate the scale. the test weight cannot
exceed the scale capacity.
lInEAr cAlIBrAtIOn
1. turn scale off and turn it back on.
2. momentarily press the lImIt and % keys together
during the initial countdown from 9 to 0 on the
display.
3. display shows 'unlOAd'. remove all weight from the
platform, then press ZErO/EntEr to set zero point.
4. display shows the first calibration weight request.
Place weight on platform.
5. Press ZErO/EntEr when stable.
6. Press ZErO/EntEr when all weight calibration is
completed. scale counts back to zero after the last
weight is selected.
NOTE: Use appropriate weights for each model
# (see below). Incorrect calibration will lead to
loss of accuracy.
