6.1 Regular error and solution
ERROR REASON SOLUTION
UUUUUU
1. Overload
2. wrong connection
with load cell
3. load cell has quality
problem.
1. reduce the weight
2. check load cell connection
3. inspection load cell. Check
the input and output
nnnnnnn
1. calibration is no good
2. wrong connection
3. load cell has quality
problem
1. check scale is resisted or
not, foot is kept level or not.
2. check load cell connection.
3. checking load cell
ERR1
not input the weights or
the weight is overload
Input the correct weights
ERR2
During calibration , the
weights is below than
Min. required weights
The calibration weights
Minimum is 10% of Max. cap.
Recommend 60%-80% of Max.
Cap.
ERR3
During calibration, the
input signal is negative
1. check the connection is
correct
2. check load cell is no
problem
ERR4
During calibration, the
signal is unstable
After the platform is stable,
start calibration
ERR5 Change PCB
