12.REPLACEMENT OF FUSE

WARNING: To avoid electric shock, disconnect measuring terminals

before removing fuse.

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

250V 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.
