    Why is the weight readout wrong on my Hanchen BSM-420.3?
    • J
      Jeff HarrisAug 7, 2025
      If the weight readout on your Hanchen Scales is obviously wrong, it could be due to a couple of reasons. First, the balance might not have been calibrated or adjusted before weighing, in which case you should calibrate or adjust the balance. Second, the balance might not have been zeroed before weighing; make sure to zero the balance before you start weighing.

      If no segments appear on the display of your Hanchen Scales, there are a few potential causes. First, check the AC power supply and ensure the power supply is plugged in. Second, the load might exceed the balance capacity, so try unloading the balance. Finally, ensure nothing is touching the weighing pan; if something is, move it.

    What to do if my Hanchen BSM-420.3 Scales display E22?

      If your Hanchen Scales are showing an E22 error, it means the poise weight is not enough. To resolve this, load on enough poise for weighing.

      If your Hanchen Scales are showing an E11 error, it indicates that the calibrate weight is wrong. To fix this, load weight on the poise to recalibrate.

      If your Hanchen Scales are showing an E12 error, it means the calibrate weight is unstable. You should eliminate the unstable factor and then recalibrate.

      To address this issue, switch on the Hanchen balance without the weighing pan. Then, place the weighing pan and restart the balance while pressing the ?? button.
