      Eric DunlapAug 3, 2025
      If your Tufner Measuring Instruments display 'ERR3', first, check all wire connections. If the issue persists, inspect the load cell and recalibrate the device. If these steps do not resolve the problem, PCB replacement may be necessary.

      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.

    Why does my Tufner T900 display UUUUUU?
    • A
      amooreAug 15, 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.

      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.
