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 the small shift errors manually, to enter shift coefficients of load cells
after changing the instrument which eliminates to perform automatic shift adjustment.
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 the numerical keys
and press
key to go to following item.
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 seen on the display. Press
key to save the changes
into the memory.
Setting Shift Coefficients of all Load cells to 1
Setting all coefficients to 1 temporary might be needed to give service to the scale without losing the shift
coefficients.
1. Press
key at the [ 544 SET TO 1 : NO
]
prompt to adjust the parameter.
2. It will be [ 544 SET TO 1 : YES
], press
key until [ SAVE : YES ] prompt seen on the display.
3. Press
key to save the changes into the memory.
Do not forget to reload coefficients after testing the scale as;
1. Press
key at the [ 544 SET TO 1 : YES
]
prompt to adjust the parameter.
2. It will be [ 544 SET TO 1 : NO
], press
key until [ SAVE : YES ] prompt seen on the display.
3. Press
key to save the changes into the memory.
