Sartorius Combics CAW1P - Scale Configuration; Adjustment without Weights

Operating Instructions Combics Indicators 27
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 fi rst
weighing platform and COm1 / WP-2, UNICOM / WP-2 or COm-WP for the second
weighing platform. 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 confi guration.
– The “Sensitivity” parameter is entered in mV/V ( see the data sheet for the
value).
h
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.
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 1.19.7.
t Close the menu access switch.
