VHE-BA-e-0810   

3.4  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. 

4  Basic safety instructions for scales 

4.1  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. 

4.2  Personnel training 

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

5  Transportation & Storage 

5.1  Testing upon acceptance 

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

5.2  Packaging 

 
Keep all parts of the original packaging in case you need to return the appliance.  
Only use original packaging for returning. 
Before sending, disconnect all connected cables and loose/movable parts.  
 

6  Unpacking and erection 

6.1  Site of installation, place of operation for scales 

The balances are designed in a way that reliable weighing results are achieved in 
common conditions of use.  
You will work accurately and fast, if you select the right location for your balance.
