Figure 9-1 Replacing the fuse 

Note

：

 

Ø

 

If the fuse blows again after replacing a fuse of the same specification, the device may 
exists  other  problems,  please  cut  off  the  power  supply  and  contact  the  after-sales 
service of our company or designated service center. 

Ø

 

Press  the  fuse  holder  downward  and  rotate  it  counterclockwise  as  shown  in  Figure 
9-1.  After  removing  the  damaged  fuse  replacing  a  new  one,  press  down  the  fuse 
holder and rotate it clockwise. 

9.8 Disposal of product scrap 

The disposal of packaging materials, waste battery and end-of-life device should obey  the 

local  laws  and  regulations,  and  user  should  treat  the  scrapped  products  and  materials  properly 
according to the laws and regulations, and try to support the classification and recycling work. 

9.9 Others 

9.9.1 Do not open the device enclosure to avoid electric shock danger. 
9.9.2  The  device  associated  circuit  schematics  and  critical  parts  list  are  only  available  to 
authorized service station or  maintenance personnel, who is responsible for maintenance of the 
device. 
9.9.3  The  device  belongs  to  measuring  instrument.  User  should  send  the  device  to  national 
designated  inspection  institution  for  inspection  according  to  the  requirements  of  the  national 
metrological verification procedure. The device shall be inspected at least once per year, and all 
the accessories should be inspected and maintained regularly (at least once every six months).
