Thank you for purchasing KAISE
"SK-8301 TRIAXIAL ELF MAGNETIC
FIELD METER"
. To obtain the maximum performance of this
instrument, read this Instruction Manual carefully, and take safe
measurement.
SK-8301 provides accurate magnetic field measurement by its triaxial
sensor and True RMS measurement method.
Confirm if the following items are contained in the package in good
condition. If there is any damage or missing items, ask your local
dealer for replacement.
Children and the persons who do not have
enough knowledge about electric measurements
must not use this instrument.
Do not measure the electricity in naked of
barefooted to protect yourself from electrical
shock hazard.
Keep away the instrument from hot and humid
conditions like inside the car. Do not apply hard
mechanical shock or vibration.
Do not polish the case or attempt to clean it with
any cleaning fluid like gasoline or benzine. If
necessary, use silicon oil or antistatic fluid.
Remove the batteries when the instrument is out
of use for a long time. The exhausted batteries
might leak electrolyte and corrode the inside.

WARNING 1. Checks of the Instrument
WARNING 2. Strong Magnetic Field
WARNING 3. Electrical Shock
WARNING 4. Measurable Frequency Range
WARNING 5. Maximum Input Observance
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.
Extremely strong magnetic field could be generated depending on
the electromagnetic sources.
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.
Do not measure any magnetic flux density that might exceed the
specified maximum input value.
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.
Be careful not to get out of safety zone or safely marking area.
The person who with implant electronic devices such as pacemaker
should avoid any dangerous area.
Be careful about displayed measurement values when approaching
uncertain magnetic field sources.
