Configuring Weighing Platforms
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 active, the parameters necessary for adjustment
without weights can be entered in the
Setup
menu under “
WP-1
" for the first
weighing platform and under
COm1 / WP-2
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 configuration.
This parameter is only available or visible with older ADCs.
– The “Sensitivity" parameter is entered in mV/V (see the data sheet for the
value). - The “Zero Point" (Offset) parameter is entered in mV/V. This parameter
is not visible with older ADCs.
h
The data entered is saved by selecting menu item 1.19.7. After saving, the data will
no longer be able to be read.
Procedure
t
Open the 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.
This applies only to 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.
Values for the zero point or the dead load are set under 1.19.7. This does not
apply to older ADCs.
t
Save the values for adjustment without weighing under menu item 1.19.8.
t
Close the menu access switch.
