13. Error Detection 

 
Automatic error diagnosis routines verify cyclically the proper function of the weighing instrument 
and ensure a faultless operation; a permanent visual control is not necessary anymore. In case of 
an error, it will be displayed in form of an error code (see table). Therefore weighing is no longer 
possible. Scale will automatically be switched off after approx. 5 seconds.
