2.4  Monitoring of Test Equipment 

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 equipment 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. 

3  Basic Safety Precautions 

3.1  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. 

 

3.2  Personnel training 

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

4  Transport and storage 

4.1  Testing upon acceptance 

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

4.2  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 put aside loose/mobile 

parts.  

  Reattach possibly supplied transport securing devices.  

  Secure all parts such as the glass wind screen, the weighing 

platform, power unit etc. against shifting and damage.
