      James HallSep 8, 2025
      If the OHAUS Scales display is showing random segments or the display locks up, it might be due to the microprocessor locking up. Try turning the power off, and then turn it back on. If the issue continues, the unit needs servicing.

    Why OHAUS AP250D Scales showing incorrect weight?

      If you are getting an incorrect weight reading on your OHAUS Scales, it could be that the balance was not re-zeroed before weighing or it is not properly calibrated. Press the ON button with no weight on the pan to re-zero it, then weigh the item. If problems persist, recalibrate the scales correctly.
