10.1.  Good Weighing Practice: 1-Load-Cell Platform Scales

 

 

In order to guarantee a long-term operation, wherein correct measurements are 
provided, the following principles must be adhered to: 

 

Load the weighing pan steadily, avoid 
applying mechanical shocks. 

 

 

 

Place  the  loads  centrally  on  the 
weighing  pan  (eccentricity  errors  are 
specified by EN 45501 standard, point 
3.6.2). 

 

 

 

Do not apply concentrated force (total 
load in one point). 

 

 

 

Avoid  side  loading,  in  particular  side 
shocks. 

 

 

 

 
 

10.2.  Good Weighing Practice: Custom Scales 

 

It is forbidden to apply load other than intended for a particular scale: 

  beam  scales;  self-supporting,  rigid  load  or  load  placed  in  rigid  load-

transferring packaging:
