TROUBLESHOOTING
Error Codes
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
Calibration is no good
Wrong connection with load
cell 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
Weight is not used during
calibration, or the weight is
above the maximum capacity
Use correct weight within the
defined range
Err2
Weight is below the minimum
requirement during
calibration.
The calibration weight
minimum is 10% of the
max. capacity set in C04.
Recommended to use 60%-
80% of max. capacity if
possible
Err3
The input signal is negative
during calibration
1. Check all wire connections
2. Check load cell
3. Recalibrate
4. PCB replacement needed if
steps 1-3 fail
Err4
Unstable signal during
calibration.
After the platform is stable,
start calibration
Err5
EEPROM Error
Change PCB
Err6
Exceed Zero Range
