Calibration Troubleshooting
If
Err 0
appears on the display during step 8, the calibration zero is out of range.
Remove all weight from the platform and press LB to perform the zero calibration
again. If this error persists, consult the raw counts table below.
If
ErrSp
appears on the display during step 10,12, 14 or 16, the span calibration is
out of range. Place the proper weight on the platform and press LB to perform the
span calibration again. If this error persists, consult the raw counts table below.
To Access Raw Counts:
1. Press and hold ZERO and REWEIGH simultaneously.
2. When the display reads
Cal 25
lb (
CAL10
kg), release ZERO and REWEIGH.
3. Press KG until the RAW A/D count is displayed.
4. Apply test weights and compare results to the table below.
5. Press KG to exit.
The following table shows the acceptable Raw Counts for no load and each
calibration point. If the scale’s raw counts are not within the ranges specified in the
following table, contact Doran’s Technical Assistance department at
