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
nnnnnn
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
Cable error
