Why is the weight value incorrect on my KERN Scales?
- R
  Roger AdamsAug 14, 2025
  An incorrect weight value on your KERN Scales can stem from several causes. It could be due to a calibration error, so try performing the calibration again using an accurate weight. Also, make sure that the platform or load cell isn't touching anything. Verify the weighing unit parameter settings are correct. Finally, check the load cell and its connectors.

What to do if the display is unstable on KERN Scales?
- A
  albertwashingtonAug 17, 2025
  An unstable display on your KERN Scales can be caused by several factors. First, make sure that goods are not touching anything around the scale. Also, check for air variations or vibrations in the environment. Temperature changes, a faulty load cell or its connections, or a faulty power supply could also be responsible. Ensure the scale is in an acceptable location, check the connectors and load cell, and verify the power supply and battery.

What to do if my KERN Scales display 'OL' or '-------'?
- S
  Stacey StoneAug 21, 2025
  If your KERN Scales are showing 'OL' or '-------', it typically indicates that the maximum capacity has been exceeded. It could also mean the load cell or mechanics are damaged, or the power supply is faulty. Ensure the platform is installed correctly, try turning the scale on again, and perform the calibration again.

Why can't I use the full capacity of my KERN MPE 250K100HNM?
- P
  Patrick McdonaldAug 25, 2025
  If you cannot use the full capacity of your KERN Scales, it might be because the overload protection stoppers or transport locks haven't been removed. Check under the platform for these. Incorrect parameter settings, an AD problem, or a damaged load cell or mechanism could also be the cause. Verify the weighing unit and parameter settings, and check the load cell.

How to fix a blank display with no self-test on KERN Scales?
- R
  Robert NicholsAug 27, 2025
  A blank display with no self-test on your KERN Scales usually indicates a power issue. The mains power might be off, the power supply could be faulty or not plugged in, the internal battery might not be charged, or there could be a problem with the on/off switch. Check that power is getting to the scale and that the on/off switch is working. Verify the voltages indicated on the power labels.

Why is the corner weight different on the platform of my KERN MPE 250K100HNM?
- D
  David ChoiAug 31, 2025
  Different corner weights on your KERN Scales platform can occur if the overload protection stoppers or transport locks haven't been removed. It could also indicate damage to the load cell or mechanism. Check for stoppers and locks under the platform. Use an accurate weight to calibrate and check the load cell.

What does it mean when KERN MPE 250K100HNM Scales display '-------' or 'NULL'?
- H
  hjohnsonSep 3, 2025
  A display of '-------' or 'NULL' on your KERN Scales suggests that the weight on the platform is below the permissible limit. It could also mean the pan isn't installed correctly, the power supply is faulty, or the load cell or mechanism is faulty. Check that the platform is installed correctly, try turning the scale on again, and perform the calibration again.

What to do if KERN MPE 250K100HNM Scales have a blank display after the self-test?
- F
  franklinrobertSep 7, 2025
  If your KERN Scales display a blank screen after the self-test, it could be due to a few reasons. The pan might not be installed, the weight might be unstable, or the load cell could be damaged. Verify that the pans are installed correctly and try turning the scale on again.

Why is the battery not charging on my KERN Scales?
- C
  chollandSep 10, 2025
  If the battery is not charging on your KERN Scales, it could be due to a few reasons: there might be a problem with the mains voltage, the charging circuit might be faulty, or there could be an issue with the battery itself. Check the mains and adapter, inspect the battery, and examine the charging circuit.
