Adjustment Without Weights

In the Service menu, adjustment without weights can be carried out by entering the
characteristic data of the load cells.

open in the Service menu.
– W hen the Service mode is activated, you can enter the necessary parameters for
adjustment without weights in the Setup menu under "WP-1" for the first
weighing platform and COm1 / WP-2, UNICOM / WP-2 or COm-WP for the second
weighing platform( only Combics2 ). The settings are made in the corresponding
Setup menu under menu item 1.19.
– T he "Nominal load" parameter must be entered in the kg unit.
– T he "Resolution" parameter must be entered in the kg unit and must correspond
to the scale interval d entered for the ADC configuration
– T he "Sensitivity" parameter is entered in mV/V (see the data sheet for the value).
The data entered are saved by selecting menu item 1.19.7. After saving, the data will

Procedure
t O pen menu access switch.
t A ctivate the Service mode.
t S elect the weighing platform.
t E nter the nominal load of the load cell(s) in kg under menu item 1.19.1. If the
weighing platform has multiple load cells, the nominal load must be multiplied
accordingly (e.g. 4 load cells, each of which has a capacity of 50 kg, will produce
a nominal load of 200 kg)
t E nter the resolution in kg under menu item 1.19.2. The value must correspond
to the scale interval d entered under menu item 11.4.1
t E nter the sensitivity of the load cells in mV/V under menu item 1.19.3.
For weighing platforms with multiple load cells: Enter the individual values of
the load cells in 1.19.3 to 1.19.6 or enter the average of all load cells in 1.19.3.
t Save the values for adjustment without weighing under menu item 1.19.8.
t Close the menu access switch.
