Monitoring of Test Resources 

In the framework of quality assurance the measuring-related properties of the balance and, if 
applicable, the testing weight, must be checked regularly. The responsible user must define a 

suitable  interval  as  well  as  type  and  scope  of  this  test.  Information  is  available  on  KERN’s 

home  page  (

www.kern-sohn.com

)  with  regard  to  the  monitoring  of  balance  test  substances 

and  the test  weights  required for  this. In  KERN's  accredited  DKD  calibration  laboratory  test 
weights and balances may be calibrated (return to the national standard) fast and at moderate 
cost. 
 

 

Basic Safety Precautions

 

 

Pay attention to the instructions in the Operation Manual 

 

Carefully read this operation manual before setup and commissioning, 
even if you are already familiar with KERN balances. 

 

Personnel training 

The appliance may only be operated and maintained by trained personnel. 

Transport and storage

 

 

Testing upon acceptance 

When receiving the appliance, please check packaging immediately, and the appliance itself 
when unpacking for possible visible damage. 

 

Packaging / return transport 

 

 

 

Keep all parts of the original packaging for a possibly required 
return. 

 

Only use original packaging for returning. 

 

Prior to dispatch disconnect all cables and remove loose/mobile 
parts.  

 

Reattach possibly supplied transport securing devices.  

 

Secure all parts such as the glass wind screen, the weighing pan, 
power unit etc. against shifting and damage.
