8. Press key to access to Shift adjustment block or press key until [ SAVE : YES ] prompt
appears on the display and press key to save the changes.
Shift adjustment method (corner adjustment)
A shift adjustment is carried out to eliminate weight reading differences placing a load on different positions
on the platform. A calibration is required after shift adjustment.
Each load cell or each sectional pair should be loaded for eccentricity adjustment. Individual shift adjustment
is used to eliminate errors in installations that have excessive eccentricity errors. Typical application of
sectional pairs are rolling loads on the platform like track scales. Sectional pairs adjustment is easier and
faster.
Automatic Shift Adjustment
IMPORTANT NOTE : This adjustment must be performed before calibration. Load the scale few times before
performing automatic shift adjustment.
Small mismatches in mechanical and electronic gain of the load sensing paths can cause the same test
weight to produce slightly different readings, depending on the location of the test weight on the scale. To
eliminate these eccentricity errors, shift adjustment is performed as
1. Press key at the [ 542 AUTO ADJUST ] prompt to start the shift adjustment.
2. At the [ ZERO CALIBRATION ] prompt, press key to go to next step.
3. [ UNLOAD THE PAN] prompt, remove any weight on the platform, then press key.
4. The terminal automatically starts to capture zero and the [ WAIT ] message indicating the operation
is in progress.
5. After the [ LOAD DLC NO : 01] or [ LOAD PAIR NO : 01] prompt, place the weight of at least 10% of
the DLC capacity as close as possible to the independent load cell or sectional pair 01. Press key.
6. The terminal automatically starts to capture the values from DLCs and the [ WAIT ] message
indicating the operation is in progress.
7. The following load cell address or pairs number appears on the display and you may repeat from
item 5 until all DLCs have been adjusted.
8. After end of adjustment the following sub-block appears.
Manual Shift Adjustment
IMPORTANT NOTE : The shift adjustment must be performed before calibration.
Manual shift adjustment is done to improve small shift errors manually entering shift coefficients of load cells
after the instrument has been changed.
1. Press key at the [ 543 MANUAL ADJUS ] prompt to start the manual shift adjustment.
2. At the [ DLC COEFF :01 ] and [ 1.0000 ] prompt, enter the coefficient by pressing key to
increase or key to decrease the blanking digit and press key to select next digit. Press
key change to the next DLC.
3. After entering the value of the last coefficient press key to check values again or press
key to exit.
4. Press key until [ SAVE : YES ] prompt appears on the display. Press key to save the
changes.
