What to do if my USA Measurements Measuring Instruments displays 'UUUUUU'?
- K
  Kelsey RogersAug 21, 2025
  If your USA Measurements Measuring Instruments shows 'UUUUUU', it could be due to several reasons. First, the scale might be overloaded, in which case you should reduce the weight. Second, there might be a wrong connection with the load cell, so you should check the load cell connection. Finally, the load cell itself may have a quality problem, requiring you to inspect the load cell and check its input/output.

What does ERR2 mean on my USA Measurements US-M5 and how do I resolve it?
- D
  Daniel DiazAug 31, 2025
  If your USA Measurements Measuring Instruments displays 'ERR2', it indicates that the weight used during calibration is below the minimum required weight. The calibration weight minimum is 10% of the max capacity set in C04. It is recommended to use 60%-80% of max capacity if possible.

  John KimAug 29, 2025
  If your USA Measurements Measuring Instruments displays 'ERR10', it means the scale was not stable when zeroed. To fix this, wait for the scale to stabilize before zeroing it.

What to do if my USA Measurements US-M5 Measuring Instruments displays 'ERR1'?
- D
  Danielle Jenkins DDSAug 28, 2025
  If your USA Measurements Measuring Instruments displays 'ERR1', it means that during calibration, either no weight was used, or the weight exceeded the maximum capacity. To solve this, use the correct weight within the defined range during calibration.

  Michelle SmithAug 27, 2025
  If your USA Measurements Measuring Instruments displays 'ERR3', it indicates that the input signal is negative during calibration. To fix this: 1. Check all wire connections. 2. Check the load cell. 3. Recalibrate the device. If these steps fail, a PCB replacement may be necessary.

What to do if my USA Measurements US-M5 displays 'nnnnnnn'?
- A
  Adam RuizAug 25, 2025
  If your USA Measurements Measuring Instruments shows 'nnnnnnn', it may be due to a few reasons. First, the calibration might not be correct, so make sure the scale is level. Second, there might be a wrong connection with the load cell, so you should check the load cell connection. Finally, the load cell itself may have a quality problem, requiring you to check the load cell input and output resistance.

  kellyreynoldsAug 23, 2025
  If your USA Measurements Measuring Instruments displays 'ERR32', it means that you are weighing over the maximum capacity or you tried to print while the scale was unstable. To resolve this, reduce the weight on the scale or print after the scale has stabilized.
