1. INTENDED USE 

 

WLC/A  precision  scales  enable  fast  and  accurate  mass  measurements  under 
laboratory and industrial conditions. The devices are equipped with an internal 
battery which allows their operation in places  where there is no access to the 
mains.  The WLC  series features  a  stainless  steel  weighing  pan,  and  a  backlit 
LCD guaranteeing clear weighing result presentation.  

 

WLC/A  precision  scales  are  equipped  with  the  following  interfaces:  
2  x  RS232,  USB  type  A,  and  USB  type  B,  wireless  communication  (option). 
The  interfaces  enable  cooperation  between  the  scale  and  peripheral  devices 
(e.g. printer, computer, USB flash drive). 

 

 

This  equipment  has  been  tested  and  found  to  comply  with 
the  limits  for  a  Class  A  digital  device,  pursuant  to  part  15  
of  the  FCC  Rules.  These  limits  are  designed  to  provide 
reasonable protection against harmful interference when the 
equipment  is  operated  in  a  commercial  environment.  
This  equipment  generates,  uses  and  can  radiate  radio 
frequency  energy  and,  if  not  installed  and  used  in 
accordance with the instruction manual, may cause harmful 
interference  to  radio  communications.  Operation  of  this 
equipment  in  a  residential  area  is  likely  to  cause  harmful 
interference  in  which  case  the  user  will  be  required  
to correct the interference at his own expense. 

 

This  equipment  has  been  tested  and  found  to  comply  with 
the  limits  for  a  Class  A  according  to  standards,  listed  in 
declaration of conformity, required by European regulations 
in order to use CE marking.  This equipment is not intended 
for  use  in  residential  environments  and  may  not  provide 
adequate 

protection 

to 

radio 

reception 

in 

such 

environments.  Class  A  products  may  also  be  utilized  in 
residential/domestic 

environments 

but 

may 

cause 

interference and require the user to take adequate corrective 
measures. 

 
 

2. WARRANTY CONDITIONS 

 

A.  RADWAG  feels  obliged  to  repair  or  exchange  all  elements  that  appear  

to be faulty by production or by construction.  

B.  Defining defects of unclear origin and means of their elimination can only 

be realized with assistance of manufacturer and user representatives.
