      Ann MorganSep 12, 2025
      If your SellEton Scales Measuring Instruments display 'UUUUUU', it could be due to several reasons: * The scale is overloaded, in which case you should reduce the weight. * There is a wrong connection with the load cell, so you should check the load cell connection. * The load cell has a quality problem, so inspect the load cell and check the input/output.
