likely to cause serious or fatal injury.

WARNING is reserved for conditions and actions that can

cause serious or fatal injury.

CAUTION is reserved for conditions and actions that can

cause injury or property damage.

Following symbols are used on the instrument and in the

instruction manual. Attention should be paid to each symbol to

ensure your safety.

Refer to this instructions in the manual.

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).

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.
