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.
