3. SAFETY PRECAUTIONS

Correct knowledge of electric measurements is essential to avoid
unexpected danger such as operator's injury or damage to the instrument.
Read the following precautions carefully for safety measurements.
,

3-1. WARNINGS

WARNING 1. Checks of the Instrument
Before measurement, check if there is no damage to the instrument.
Dust, grease and moisture must be removed.
WARNING 2. Strong Magnetic Field
Extremely strong magnetic field could be generated depending on
the electromagnetic sources.
1. Be careful not to get out of safety zone or safely marking area.
2. The person who with implant electronic devices such as pacemaker
should avoid any dangerous area.
3. Be careful about displayed measurement values when approaching
uncertain magnetic field sources.
WARNING 3. Electrical Shock
Do not touch the instrument on voltage generated circuit or any other
parts. It might cause electrical shock hazard that could result in serious
injury or even death.
WARNING 4. Measurable Frequency Range
Measurable frequency range of this instrument is 40Hz to 1kHZ.
Measurement out of this range should be incorrect, and may not
detect the strong magnetic field which is dangerous for the person
who with implant electronic devices such as pacemaker.
WARNING 5. Maximum Input Observance
Do not measure any magnetic flux density that might exceed the
specified maximum input value.
