9.2.2 Eccentricity Adjustment
The eccentricity adjustment must be done in parameter group [32-] before the calibration of the scale. The
adjustment can be done for each load cell independently or for sectional pairs. The selection is done by
parameter [320]. After selection of the adjustment method , the adjustment is performed automatically as
described in parameter [321].
[32-] DLC Eccentricity Adjustment Block
In this parameter group the eccentricity correction is performed automatically or manually. This
adjustment must be performed automatically before calibration.
[320 X] Adjustment Method
The scale eccentricity can be adjusted in corners (each DLC individually) or in sectional pairs.
0 = Independent DLC (factory default) 1 = Sectional pair
[321 ] Auto Adjustment
After entering parameter [321] by pressing the key, you will see [Zero CA] on the display. Unload
the scale and press the key. Do not interfere the scale during the period the [Waıt] message is
displayed. Next the instrument will display [321 01]. Place a weight of at least 10% of the DLC capacity
as close as possible to the independent load cell or sectional pair 1. Then press . After some
period [321 02] appears on the display. Apply the same load to the other places in sequence.
After loading all load cells / sections the message [322 ] will be shown on the display. This means the
eccentricity error correction is performed automatically.
[322 ] Manual Adjustment
If needed the eccentricity error can get modified manually. You can change the error correction
coefficients of the DLCs in this parameter. For entering this parameter press the key. You can
change the load cell number by the key. For changing the coefficient of any DLC select the
number of the DLC and press the key to view and edit the coefficient. Use the numerical keys for
changing the value and then press the key.
To exit this parameter press the key and save the changes you applied by pressing . The
key is used to quit without saving the manual corrections.
[323 X] Service mode: Set Shift Coefficients manually to 1
This parameter allows you to view the weighbridge’s performance with disabled eccentricity correction for
service purposes. Using this function does not change any stored coefficient but all coefficients are
“temporarily” set to value 1.
0 = Normal operation (factory default) 1 = Service mode
Attention:
After the eccentricity adjustment a scale calibration has to be done.
