Caution:   

Dispose the used batteries according to the rules, which are defined by each 
community. 

Warning:

   

If an explosion or fire hazard could occur through fitting a battery of the wrong type. 
 

5.    Fuse replacement 
 

1)    This meter is provided with a F0.5A/600V fuse to protect the resistance, Diode,

 

 

Audible continuity test and the current measuring circuits which measure up to 

 

200mA, with a F10A/600V fuse to protect the 10A range. 

2)    Ensure the meter is not connected to any external circuit, set the selector switch 

 

to “

OFF

” position to power off and remove the test leads from the terminals. 

3)    Remove the screw on the battery cover to lift the battery cover, and remove the 

 

two screws on the bottom case, loose the button stand upward side the battery 

 

box of the front case and lift the bottom case. 

4)     Replace the old fuse with the same type and rating: 
      5×20mm F0.5A/600V or 5×20mm F10A/600V fuse. 
5)    Close the bottom case and the battery cover and fasten the screws. 
 

6.    MAINTENANCE 
 

1)    Before open the bottom case, disconnect both test lead and never uses the 

 

meter before the bottom case is closed. 

2)    To avoid contamination or static damage, do not touch the circuit board without 

 

proper static protection. 

3)    If the meter is not going to be used for a long time, take out the battery and do 

 

not store the meter in high temperature or high humidity environment. 

4)    Repairs or servicing not covered in this manual should only be conducted by 

 

a qualified person. 

5)    Periodically wipe the case with a dry cloth and detergent. Do not use abrasives 

 

or solvents on the meter.
