WARNINGS
1. Never open the instrument when making measurements.
2. If the instrument shows the following conditions, do not try to
make measurements and have the instrument checked for
inspection or repair.
a) Instrument shows visual damage.
b) Test leads are damaged.
c) Instrument can not be operated for intended measurements.
d) Instrument has been stored for a long period of time
under abnormal conditions.
e) Instrument has been subjected to severe shocks and
vibrations.
3. High voltage may be present with high energy levels.
Connect the leads to the system carefully with fingers behind
all finger guards.
4. If the all open phase lamps are not lit on, any phase may still
be live-be carefull.
CAUTIONS
1. Make sure to never apply a voltage more than 600V ACrms.
between the test leads of the instrument and earth to avoid
damage to the instrument.
2. Do not measure for more than five minutes when measuring
on 500V AC or more, although the instrument is designed for
the use 110V through 600V AC.
Measurement categories (Over-voltage categories)
To ensure safe operation of measuring instruments, IEC61010
establishes safety standards for various electrical environments,
categorized as CAT.Ⅰ to CAT.Ⅳ, and called measurement
categories. Higher-numbered categories correspond to
electrical environments with greater energy, So a measuring

instrument designed for CAT.Ⅲ environments gives greater
protection than one designed for CAT.Ⅱ.
CAT.Ⅰ: Equipment connected to a mains outlet socket
CAT.Ⅱ: Fault category level at a mains socket
CAT.Ⅲ: Fault category at distribution board level
CAT.Ⅳ: The circuit from the service drop to the power meter and
primary over-current protection device (distribution
panel).
FEATURES
●Two Functions in One Unit
KEW8031F is designed to check phase sequence. Lamps
provided on the unit will also tell you if a phase is open.
●Highly Reliable
Can check a wide range of 3-phase power source from 110V to
600V. Sealed against dust, the unit ensures trouble-free
performance.
