0 5. Never use meter if the meter or test leads are damaged or broken.
0 6. Never use uncased meter.
0 7. Be sure to use a fuse of the specified rating or type. Never use
a substitute of the fuse or never make a short circuit of the fuse.
0 8. Always keep your fingers behind the finger guards on the
probe when making measurements.
0 9. Be sure to disconnect the test pins from the circuit when
changing the function or range.
10. Never use meter with wet hands or in a damp environment.
11. Never open tester case except when replacing batteries or
fuse. Do not attempt any alteration of original specifications.
12. To ensure safety and maintain accuracy, calibrate and check
the tester at least once a year.
13. Indoor use.

1. Correct measurement may not be performed when using the
meter in the ferromagnetic / intense electric field such as
places near a transformer, a high-current circuit, and a radio.
2. The meter may malfunction or correct measurement may not
be performed when measuring special waveform such as that
of the inverter circuit.
