WARNING:

 To avoid electric shock, disconnect measuring terminals 

before removing fuse. 

CAUTION:

 for continued protection against fire, replace only with 0.3A, 

250V fuse.

12.REPLACEMENT OF FUSE

1. Use a phillips screwdriver to remove the screw on the back cabinet. Pull 

apart the front and back cabinets.

2. Replace the fuse with a new fuse of the same type / rating (0.3A, 250V)
3. Do not touch any inside area other than the fuse.

13. TIPS FOR BEST HANDLING

1. Always observe correct polarity: red lead to positive and black lead to 

negative terminal.

2. When checking unknown voltages, use the highest range first and 

gradually decrease until readings are obtained.

3. For exact readings, look at the scale from the point where the pointer and 

its reflection in the mirror come together, otherwise a reading error due 
to parallax will result.
