Calibration
Errors
1
Calibration Timeout
- Restart calibration
2
ADC Error
- Re-energize the instrument
- If seen again, change the board.
3
Instrument cannot be calibrated
- Check load cell cable
- Re-energize the instrument
34
Instrument cannot be calibrated
- Load cell signal is very low or too high
35
Calibration Error
- Calibration test weight is not enough
- Increase calibration weight value (40011)
- Check load cell connections
37
Scale unstable
- Wait until scale become stable
- Check grounding wiring
