# This symbol is marked where the user must refer to the instruction
manual so as not to cause personal injury or instrument
damage.
Indicates an instrument with double or reinforced insulation.
This instrument satisfies the marking requirement defined in the
WEEE Directive (2002/96/EC). This symbol indicates separate
collection for electrical and electronic equipment.
# DANGER
●Never make measurement on a circuit in which earth
potential of 600V or higher exist.
●Do not attempt to make measurement in the presence of
flammable gasses, fumes, vapor or dust. Otherwise, the use
of the instrument may cause sparking, which can lead to an
explosion.
●Never attempt to use the instrument if its surface or your
hand is wet.
●The instrument should be used only in its intended
applications or conditions. Otherwise, safety functions
equipped with the instrument do not work, and instrument
damage or serious personal injury may be caused.
●Verify proper operation on a known source before use or
taking action as a result indication of the instrument.
●Keep your fingers and hands behind the protective
fingerguard during measurement.
# WARNINGS
●Never attempt to make any measurement, if the instrument
has any structural abnormality such as cracked case and
exposed metal part.
●Stop using the test lead if the outer jacket is damaged and
the inner metal or color jacket is exposed.
●Do not install substitute parts or make any modification to
the instrument. Return the instrument to Kyoritsu or your
distributor for repair or re-calibration.
●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.The maximum time indicated
above is measured from the time when more than 2 test
leads of the unit are connected to the power supply cords.
●Exceeding the limited continuous testing duration or leaving
the instrument connected to the circuit under test may heat
the internal circuit and cause burn injuries or fire..
●If the all open phase lamps are not lit on, any phase may still
be live-be carefull.
# CAUTIONS
●Do not expose the instrument to the direct sun, extreme
temperatures or dew fall.
●Use a damp cloth and detergent for cleaning the instrument.
Do not use abrasives or solvents.
●This instrument isn't dust & water proofed. Keep away from
dust and water.
Measurement categories (Over-voltage categories)
To ensure safe operation of measuring instruments, IEC61010
establishes safety standards for various electrical environments,
categorized as 0 to CAT Ⅳ, and called measurement
categories. Higher-numbered categories correspond to electrical
environments with greater energy, So a measuring instrument
designed for CAT Ⅲenvironments gives greater protection than
one designed for CAT Ⅱ.
O(None, Other): Circuits which are not directly connected to
the mains power supply.
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).

DESIGNATIONS
SAFETY WARNINGS
This instrument has been designed and tested according to IEC
Publication 61010; Safety Requirements for Electronic Measuring
Apparatus. This Instruction manual contains warnings and
safetyrules which must be observed by the user to ensure safe
operation of the instrument and retain it in safe condition.
Therefore, read through these operating instruction before using
the instrument.
The voltage values used in this manual or on the meter are given
in line voltage, unless otherwise specified.
O: Device which is
not directly
connected to the
mains power supply

OPERATING INSTRUCTIONS
(1) Connect colour coded alligator clips or prods to the terminals
of a 3-phase power source where a rotating electrical machine
such as a motor will be connected or input to a building.
(2) Press the push switch button located on top of the unit.
Keep this button pressed during phase sequence or open
phase check. When the push switch button is released it
immediately goes off.
(3) Make sure that all of the three lamps for phase check are on.
If so, there is no open phase. When any of the three lamps is
Not on there is open phase.
Open phase check Open phase on terminal
Lamp "L1" is not on where Red alligator clip
is connected.
Open phase check Open phase on terminal
Lamp "L2" is not on where Whight alligator clip
is connected.
Open phase check Open phase on terminal
Lamp "L3" is not on where Blue alligator clip
is connected.
*When the open phase check lamps are not on the rotating disc
does not turn.
(4) Check the rotating direction of the inside disc through the
phase sequence indication window.
*When the rotating disc turns counter-clockwise alternate the
connection of the two of the three alligator clips. Then, the
rotating disc will turn clockwise.
*When the rotating disc turns clockwise phase sequence is
L1,L2 and L3 in order of the power source terminals where the
Red, Whight and Blue alligator clips are connected.
