Precautions for Safety Measurement
To ensure that the meter is used safely, follow all safety and
operating instructions.
1
1. This meter is a clamp meter exclusive for low voltage. Use it
only for circuits of 600V or below. If it is used for measuring
the circuit exceeding 600V, it may cause electrical shock or
damage to the meter.
1
2. Pay special attention when measuring the voltage of AC 33
Vrms (46.7V peak) or DC 70V or more to avoid injury.
1
3. Never apply an input signal exceeding the maximum input value.
1
4. Never use meter if it is damaged or broken.
1
5. During testing, never hold the iron core side of the meter
ahead of its barrier.

6. Test leads:
・
Be sure to use the specified model of test leads.
・
Never use the test bar or cord that is damaged.
・
During testing, never hold the test pin side of the test bar
ahead of its finger guard.

7. In case of the models using fuses, be sure to use a fuse of
the specified rating and type.
Never use a substitute of the fuse or never make a short,
circuit with a lead wire.
1
8. Never use meter in the state that its case or battery cover is
taken off.
1
9. Be sure to disconnect the test pins from the circuit when
changing the function or range.
10. Before starting measurement, make sure that the function
and range are properly set in accordance with the measurement.
11. Never use meter with wet hands or in a damp environment.
12. Never open meter case except when replacing batteries or
fuses.
13. Do not attempt any alterations of original specifications.
14. To ensure safety and maintain accuracy, calibrate and check
the meter at least once a year.
15. When making an measurement of distorted AC wave shape
other than AC sinusoidal wave.
Pay attention not to become the state of overload, since the
value may be indicated (displayed) less than an actual value.
16. Indoor use.
