Troubleshooting
Error Messages
EEPROM failure. Scale will require recalibration
AD converter failure. Circuit board may need to be repaired or
replaced.
Self-test shunt-current circuitry has detected one or multiple load cell
errors. A load cell may have failed or there is a bad connection. "XX"
represents the cell or connection that has failed: xx = 1-8 (single digit)
if there is a single load cell failure, or xx = 2-digit hex code if multiple
cells failed. (Examples: "" = load cell # 2 error, "" = load
cells #1- #4 errors)
Run-time overload limit circuitry has detected one or multiple load cell
errors. A LC may have failed or there is a bad connection. "xx"
represents the cell or connection that has failed: xx = 1-8 (single digit)
if there is a single load cell failure, or xx = 2-digit hex code if multiple
cells failed. (Examples: "' = load cell # 2 error, "" = load cells
#1- #4 errors)
Low battery. Replace the battery or connect the charger if using
rechargeable batteries. (WARNING: Do not charge alkaline cells)
Overcapacity. Reduce load to scale.
Zero Range Error. Scale attempted to zero off a load outside the range
specified in the zero range setting. Remove load applied to scale and
press zero.
Display error. Number is too large to fit on the display.
Diagnostic power-up messages. The messages will not affect normal
operation and can typically be ignored.
Certain conditions for accumulation have not been met and the
attempted scale accumulation was rejected. The scale will not
accumulate and will display the error message "." if the current
weight is negative, zero or the weight is in motion. Only one
accumulation is allowed while weight is on the scale(s). The weight
should be temporarily removed between accumulations. Refer to the
"Accumulating Print Axle" section for additional information.
Refer to the “Totalizing Setup” section for setup details. Or press
LOCAL/TOTAL to change to the standard LOCAL display if totalizing is
not needed
