Range
This parameter is required for evaluations in the unit %.
• Under Set displays, enter the value that is to correspond to the gross value 100 % in the (before
selecting %) selected unit kg, N, cbm or pcs (see section 7.2). Values between 0 and the maximum
cell load are possible.
• Alternatively, you can select Execute and then Yes after excitation of the cell (e. g. after applying
a corresponding weight). This stores the current measured value as Range.
After a change to the unit %, the gross value is calculated as follows:
kg/unit
• This menu option is only displayed if N, cbm or pcs has been selected as unit (see section 7.2) or
if % has been selected as unit and N, cbm or pcs has been selected previously.
• The entered value determines the conversion of kg into
− N (approx. 1/9.81 = 0.102)
− cbm (known from the application or to be determined by weighing)
− pcs (known from the application or to be determined by weighing).
• If % has been selected as unit, the factor for converting kg into the previously selected unit must
be entered.
• If an adjust into a unit other than kg is performed, the value kg/unit must be entered before the
adjust. After changing the value kg/unit, a new adjust is required.
