8.1 Cleaning 

Only use a cloth dampened with mild suds and not aggressive 
cleaning agents (solvents or similar). Please ensure that fluids

soft cloth.  Loose sample residue/powder can be removed 
carefully using a brush or hand vacuum cleaner. 

8.2 Maintenance,

The operating company shall ensure that load-bearing com-
ponents are checked by a competent person at maximum 
intervals of one year.  
These checks can be necessary at intervals shorter than one 
year depending on the conditions of use. This applies, for 
example, in the case of particularly frequent use, increased 
wear and corrosion.   
 
The device may only be opened by trained service engineers 
authorised by KERN.   
Disconnect from the mains supply before opening.

the device in compliance with the valid national or regional law

Interruption Possible 

cause 

 

The balance is not switched on. 

Weight display is 
not illuminated. 

 

The batteries are wrongly inserted, the 
batteries are empty 

 

 

No  batteries are attached  

 

Draught/air movement 

 

Table/floor vibrations  

The weight dis-
play changes 
continually   

  Vibrations on the balance suspension

 

 

Electromagnetic fields / static charging 
(choose different location/switch off inter-
fering device if possible) 

 

The balance display is not set to zero  

 

Adjustment is no longer correct. 

The weighing 
result is obviously 
incorrect 

 

Great fluctuations in temperature. 

 

Electromagnetic fields / static charging 
(choose different location/switch off inter-
fering 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.
