5  Troubleshooting 

 
 

Interruption 

Possible cause 

==

OVERLOAD

== 

 

  Either the scale is overloaded or there is a mechanical 

defect 

= ============ 

 

  Underload: Weighing range has been fallen short of 

  Mechanical defect or a defect in the main PCB 

           

<<

            . 

 

  In counting and % mode: part too light 

           

bat

            . 

 

  The rechargeable battery is empty and should be 

loaded 

Weight display is not illuminated. 

  The balance is not switched on. 

 

  The mains supply connection has been interrupted 

(mains cable not plugged in/faulty). 

 

  Power supply interrupted. . 

The weight display changes continually   

 Draught/air 

movement 

 

  Table/floor vibrations  

 

  The weighing plate is in contact with foreign matter. 

  Electromagnetic fields / static charging (choose different 

location/switch off interfering device if possible) 

The weighing result is obviously incorrect 

  The balance display is not set to zero  

 

  Adjustment is no longer correct. 

 

  Great fluctuations in temperature. 

  Electromagnetic fields / static charging (choose different 

location/switch off interfering device if possible) 

 

 
Switch the balance off if other error messages should appear and then switch on again. 
Contact the manufacturer if the error message does not disappear.
