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. At [
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 ]
prompts, 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 shown 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 shown 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 shown on
the display.
3. Press
key to save the changes into the memory.
