Measurement Categories (Overvoltage categories)
To ensure safe operation of measurement instruments, IEC 61010
establishes safety standards for various electrical environments, catego
rized as CA T I to C AT IV, and call ed measurement cat egories. The se are
defined as follows.
CAT I : Secondary electrical circuits connected to an AC electrical
CAT II : Primary electrical circuits in equipment connected to an AC
CAT III : Primary electrical circuits of heavy equipment (fixed installa-
CAT IV : The circuit from the service drop to the service entrance, and
Higher-numbered categories correspond to electrical environments with
greater momentary
energy. So a measure
ment device designed for
CAT III envir onment s can
endure greater momen
tary energy than a device
designed for CAT II.
Using a measurement instrument in an environment designated with a
higher-numbered category than that for which the instrument is rated
could result in a severe accident, and must be carefully avoided.
Never use a CAT I measuring instrument in CAT II, III, or IV enviro nment s.

Operating Precautions
• The instrument and the 3471 and 3472 Magnetic Field Sensors are
built mainly from nonmagnetic metals and contain hardly any mag
netic materials. Thus if the inst rument is heated by an all metal IH and
other induction heating system the sensor may melt or be damaged,
because of the nonmagnetic metals.
• The 3471 and 3472 Magnetic Field Sensors have a plastic housing that
may melt if brought into contact with a hot measurement object (cookpot
or other hot object).
• Do not expose cables t o exces siv e str ess as they may br eak . Esp ec iall y,
the 9758 Exten tion Ca ble and 975 9 Output C able shou ld be hand led with
care.
Handling with the CD
• Always hold the disc by the edges, so as not to make fingerprints on
the disc or scratch the printing.
• Never touch the recorded side of the disc. Do not place the disc
directly on anything hard.
• Do not wet the disc with volatile alcohol or water, as there is a possibility of the label printing disappearing.
• To write on the disc label surface, use a spirit-based felt pen. Do not
use a ball-point pen or hard-tipped pen, because there is a danger of
scratching the surface and corrupting the data. Do not use adhesive
labels.
• Do not expose the disc directly to the sun's rays, or keep it in conditions of high temperature or humidity, as there is a danger of warping,
with consequent loss of data.
• To remove dirt, dust, or fingerprints from the disc, wipe with a dry
cloth, or use a CD cleaner. Always wipe radially from the inside to the
outside, and do no wipe with circular movements. Never use abra
sives or solvent cleaners.
• Hioki shall not be held liable for any problems with a computer system
that arises from the use of this CD, or for any problem related to the
purchase of a Hioki product.

Exposure level (general public):
This level is used f or measuring exposur e to magnetic fields prevalent in environments where we can
assume the presence of people of all age groups and
health conditions (people who are not normally
aware of the presence of magne tic field s) as well as
exposure to magnetic fields gener ated by appli anc
es and other consumer devices manufactured to
conform to EN50366 (or IEC6233) and other st an
dards.
This level corresponds t o the general public exp osure level in ICNIRP 1998.
Exposure level (occupational):
This level applies to measurements of exposure to
magnetic fields in environments that involve
adults only who are generally exposed under
known conditions and are trained to be aware of
potential risk and to take ap propriate prec autions.
This level corres ponds to the occupational ex po
sure level in ICNIRP 1998.

Use the exposure level figures indicated for the general public in IEC62233 or Since
the reference levels for magnetic field exposure indicated in ICNIRP1998 for occu
pational exposure is approximately five times that of general public exposure, the indicated values for occupational exposure is roughly a fifth of general public exposure.

3.4.2 Exposure Level
• Values obtained in an exposure measurement are not measures of
the risk a specific magnetic field poses.
• In Exposure Level mode, first order filters are used to approximate
magnetic density flux levels in the ICNIRP guideline. Thus corner
frequencies cause a difference of at most 3 dB, but this corresponds
to the "smoothed edges" referred to in IEC62233 or EN50366.
• A discussion of acute health effects of exposure must acco unt for coupling factors such as the human body and magnetic fields, threshold
values under basic restrictions and safety factors (reduction factor) for
general public and occupational exposure.
Reference:
In IEC62233, the coupling factor at 10 cm as described in ICNIRP is
"0.14" for small and "0.16" for large ones while the safety factor
(reduction factor) (the reduction factor for public exposure is "50" (1/
50 of the threshold value) for threshold values for occupational expo
sure is "10" (1/10 of the threshold value).
For details, see "Appendix" (P . 111).
