8. CHECKING AND ADJUSTING THE CORNER LOAD
A. Testing the Corner Load:
B. Adjusting the Corner Load
1.
Set the highest readability for test purposes in the indicator set up mode for improved checking of changes
resulting during adjustment.
Weighing range 300 kg, readability 0,02 kg
Weighing range 600 kg, readability 0,05 kg
Weighing range 1500 kg, readability 0,1 kg
Weighing range 3000 kg, readability 0,2 kg
2.
Access the connection box and activate the adjustment potentiometer.
W 3
W 2
C. Adjustment at Analogue PCB
The load cell 1 is adjusted using the potentiometer pair 1, load cell 2 at pair 2, etc.
The hook/DIP switches on the analogue PCB must be opened for this purpose.
Place appropriate test weights (see overview in Section 7) in the
centre of the load plate and tare.
Scale shows -0-.
Place test weights in succession at all four corners.
Deviations are displayed with a sign.
Record values.
If the deviations lie outside the tolerances listed in Section 7,
adjustment is necessary.
Adjustment Rule:
The corner (load cell) with the greatest negative deviation must
W
4
be set to zero.
Do not change the setting of this corner, even after repeated
adjustment cycles.
Adjustment of the Corner Load:
W1
Start by adjusting the corner at which the greatest positive
deviation was found.
With a positive deviation: turn both
potentiometers the same number of
rotations to the right
With a negative deviation: turn both
potentiometers the same number of
rotations to the left
