Calibration and Adjustment
Sequence
In the Setup menu, you can configure
the scale so that:
– calibration is always followed
automatically by adjustment
Calibrate, then auto
adjust or
– you have the choice of ending the
sequence or starting adjustment
after calibration
Calibrate,
then manual adjust
(factory setting)
If no deviation is determined in
calibration, or the deviation is within
the tolerance limits dictated by the
degree of accuracy you require, it is
not necessary to adjust the scale. In
this case, you can end the calibration/
adjustment sequence after calibration.
There are 2 soft keys active at this
point:
–
Start to start adjustment
– End to end the sequence

the required tolerance of the display
accuracy.
