> If the setting

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 (factory setting) or
– you have the choice of ending the
sequence or starting adjustment 
after calibration 
Calibrate,
then manual adjust
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
