Error Codes
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. Inspect load cell; Check the input/output
4. See Q&A section
nnnnnnn
1. Calibration is no good
2. Wrong connection with load cell
3. Load cell has quality problem
1. Make sure scale is level
2. Check load cell connection
3. Check load cell input and output resistance
4. See Q&A section
ERR1
During calibration, weight is not used or
the weight is above the max. capacity
Use correct weight within the defined range
ERR2
During calibration, the weight is below
the minimum required weight
The calibration weight minimum is 10% of
the max. capacity set in C04.
Recommended to use 60%-80% of max.
capacity if possible
ERR3
During calibration, the input signal is
negative
1. Check all wire connections
2. Check load cell
3. Recalibrate
4. PCB replacement needed if steps 1-3 fail
ERR4
During calibration signal is unstable
After the platform is stable, start calibration
ERR5
EEPROM Error
Change PCB
ERR6
Exceed Zero Range
Remove the load and See Q&A section
ERR9
The number to chick is too big
Input again with proper number
ERR10
No information
The accumulation is empty
