Adjustment Without Weights
In the Service menu, adjustment without weights can be carried out by entering the
characteristic data of the load cells.
3
Adjustment without weights may not be carried out on weighing equipment used
in legal metrology.
Setup information – Adjustment without weights is only possible when the menu access switch is
open in the Service menu.
– When 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.
– The “Nominal load” parameter must be entered in the kg unit.
– The “Resolution" parameter must be entered in the kg unit and must correspond
to the scale interval d entered for the ADC configuration
(only for older ADCs).
– The “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
no longer be able to be read.
Procedure
t Open menu access switch.
t Activate the Service mode.
t Select the weighing platform.
t Enter 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 Enter 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 (only for older ADCs).
t Enter 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.
