Calibration Troubleshooting - Doran DS5200 Technical Manual

Calibration Troubleshooting

If gruL or groL appears on the display, the calibration zero is out of range.
Check connections between the indicator and base. Press BMI to perform the
zero calibration again. If this error persists, consult the raw counts table.
If ErSp appears on the display, the span calibration is out of range. Place the
proper weight on the platform and press BMI to perform the span calibration
again. If this error persists, consult the raw counts table.
If Erng appears on the display, the span calibration has detected a negative
range. If this error persists, consult the raw counts table.
The following table shows the acceptable Raw Counts for no load and full load.
Raw Counts can be viewed through the last setup parameter. Refer to
Parameter Setup, for more information regarding parameter viewing.
If Ernn appears on the display, there is excessive motion on the scale platform.
If the scale's raw counts are not within the ranges specified in the following table,
contact Doran's Technical Assistance department at tech@doranscales.com.
