Check the AC adapter and power supply connections if nothing appears on the display. Press the "automatic shutoff - off" option in the Setup menu or the power button to verify the balance is on. If your machine does not work properly, go to the next step.
Remove some of the fragments from the balance to lower the weight if "H" is displayed; otherwise, go to the next step.
Re-seat the weighing pan if "L or Err 54" is displayed; otherwise, go to the next step.
Reduce the input text if "Too many char." is displayed. A maximum of 20 characters is the limit for "S ID," "NUM," "L ID" and "ID." A maximum of 14 characters is the limit for "W ID." If this error message does not apply to your machine, go to the next step.
Contact your local Sartorius repair technician for service if "Err 30," "Err 31," "Err 10x," Err320" or "No WP" is displayed. These errors pertain to printer output blockage, interface interruptions, stuck keys, memory problems and a defective weighing cell, respectively. If another error message is shown on the display, go to the next step.
Match the error message shown on the display to the one shown in your machine user's manual. Apply the recommended solution. If your machine does not work correctly, contact your local Sartorius repair technician for additional support.
