6.14.2.4 Adjustment with weight
1. Click [by load] in the task bar.
2. Enter the weight value of the calibration weight in the line [Adjusted at].
3. Place the calibration weight on the scale.
4. Click [Adjust] in the task bar.
Weight value, weight unit and measuring signal in mV/V
corresponding to this value are displayed in the line [Adjusted at]
5. Save the adjustment.
6.14.2.5 Adjusting with calculated mV/V value
The scale can be adjusted without weights. During input of the load cell mV/V
value, the acceleration of gravity at the place of installation can be taken into
account.
The PR- load cell data is based on the acceleration of gravity in Hamburg,
Germany:
9.81379 m/s

.
Calculating Span
Span indicates the equivalent input voltage in mV/V related to the maximum
capacity (Max) of the scale. It is calculated as follows:
Span [mV/V] = max. capacity (Max) × load cell sensitivity C
n
[mV/V] / load cell
capacity (max. capacity E
max
× number of load cells)
load cell sensitivity C
n
= rated output C
n
(see technical data for the load cell).
Adjusting with mV/V
1. Click [by mV/V] in the task bar.
2. Enter the calculated Span value in the line [Adjusted at].
3. Click [Adjust] in the task bar.
Weight value, weight unit and measuring signal in mV/V
corresponding to this value are displayed in the line [Adjusted at].
4. Save the adjustment.
