      Patrick FigueroaAug 21, 2025
      If your Optima Scale Accessories shows 'ERR3' during calibration, this indicates a negative input signal. First, check all wire connections. Second, check the load cell. Third, recalibrate the scale. If these steps fail, a PCB replacement may be needed.

      Dustin GrayAug 25, 2025
      If your Optima Scale Accessories displays 'ERR2' during calibration, it means the weight used is below the minimum required weight. The calibration weight minimum is 10% of the maximum capacity set in C04. It is recommended to use 60%-80% of max capacity if possible.

      Kevin MackAug 28, 2025
      If the Optima Scale Accessories displays 'nnnnnnn', it could be due to calibration issues. Make sure the scale is level. Another potential cause is a wrong connection with the load cell, so check the load cell connection. Also, the load cell might have a quality problem, so check the load cell input and output resistance.

      Nicholas CookAug 30, 2025
      If your Optima Scale Accessories displays 'ERR1', it indicates that during calibration, either no weight was used, or the weight exceeded the maximum capacity. Use the correct weight within the defined range.

      marshalljaimeSep 3, 2025
      If your Optima Scale Measuring Instruments displays 'UUUUUU', it could be due to several reasons. First, you might be overloading the scale, so reduce the weight. Second, there might be a wrong connection with the load cell, so check the load cell connection. Finally, the load cell itself might have a quality problem; inspect the load cell and check its input/output.

      If your Optima Scale Measuring Instruments displays 'nnnnnnn', it could be due to a few potential issues. First, the calibration might be off, so ensure the scale is level. Second, there might be a wrong connection with the load cell, so check the load cell connection. Third, the load cell itself might have a quality problem; check the load cell input and output resistance.

      Martin BrownSep 7, 2025
      If your Optima Scale Measuring Instruments shows 'ERR3' during calibration, it indicates that the input signal is negative. Here's what you can do: 1. Check all wire connections. 2. Check the load cell. 3. Recalibrate the device. 4. If the previous steps fail, a PCB replacement may be necessary.
