      If your Tufner Measuring Instruments display 'ERR2', ensure that the calibration weight is at least 10% of the maximum capacity set in C04. It is recommended to use 60%-80% of the maximum capacity, if possible.

      Matthew ReedAug 18, 2025
      If your Tufner Measuring Instruments display 'UUUUUU', it could be due to several reasons: the weight might be too high (overload), there could be a wrong connection with the load cell, or the load cell itself may have a quality problem. To resolve this, first, reduce the weight on the instrument. Then, check the load cell connection. Finally, inspect the load cell and check its input/output.

      Angela GomezAug 23, 2025
      If your Tufner Measuring Instruments display 'nnnnnnn', there could be a few reasons: the calibration might not be correct, there may be a wrong connection with the load cell, or the load cell itself might have a quality issue. To address this, first, make sure the scale is level. Next, check the load cell connection. Then, check the load cell's input and output resistance.
