Thank you for your purchase of our product.
Read this instruction manual carefully before installation, wiring, and using this product.
Safety concerns
 Environment and conditions of usage
Please be sure to use this product in a place that meets the following conditions.
In places that do not meet this condition, it may cause malfunction or failure and product life decline.
 Within the range of ambient temperature -10 to +55 ℃, humidity 85％ RH or more.
 Place free of dust, corrosive gas, salt and oily smoke. (Corrosive gas：SO2
/ H2S, etc.)
 Location that is not affected by vibration and shock.
 Location that is not affected by external noise.
 Altitude 1000m or less.
 If this unit directly measures an inverter output of cycle control, SCR phase angle control or PWM control,
an error may increase due to its operation principle.
 The precautions at the case of using by outdoor panel.
 These products are not a dustproof construction, waterproof construction, and splash proof construction.
Please avoid the place with much dust. Moreover, please install in the place which requires neither rain
nor waterdrop.
 Please do not install in the place where sunlight hits directly.
Discoloration and degradation of a name plate, and cover is deformed by the surface temperature rise.
 Installation and wiring
Installation and wiring, refer to the instruction manual, please be conducted by engineers.
And, please observe the following notes.
 Please wire after the connection diagram is checked.
 Please forbid a hot line work.
 Please use the size of the electric wire that is suitable for conducting current.
 Please securely tighten the terminal screws. Please make sure that forgotten tightening
of the terminal screw is not.
 Preparation before use
At the case of connect this product to the main power supply directly, please put the suitable fuse to the outside.
This product must be set before use. Reading this instruction manual, please set correctly.
 About dew condensation
If the temperature and humidity of an installation change rapidly when a product is a non-energization, the
waterdrop by dew condensation may adhere to a display inner side. (The display filter and the LCD surface
stick and the pattern of the shape of a circle or an ellipse occur.)
This phenomenon is not trouble. It will disappear, if a control power supply is applied and about 2 hour passes.
 Maintenance
 Inspection of energized is dangerous.
 There is no parts to be replaced on a regular inspection.
 Please wipe off lightly with the dry soft cloth. When it wipes with the damp cloth or the dry cloth strongly, a
surface is damaged. And, the character of a name plate may disappear.
Please do not use the organic solvent, chemicals, cleaners, etc., such as an alcohol, for cleaning.
The liquid crystal display (LCD) may light during cleaning on the LCD face. However, this phenomenon is caused by
the static electricity that may be produced in the filter, and it does not show any trouble.
Leave the unit as it is for a while, and the display goes out due to natural discharge.
Do not press the LCD face strongly, otherwise it may be broken. When the filter has been pressed, it may touch the
LCD face to stain the LCD face. However, this phenomenon does not show any trouble, but it is caused by a change
of the ambient environment or the like. The LCD face may be restored to its original condition after a while during
the use as it is.

 The average temperature (day) 40 ℃ or less.
 Place free of dust, corrosive gas, salt and oily smoke.
 Location that is not affected by vibration and shock.
 The aluminum electrolytic capacitor is used for a product. Please do the energization of the power
supply within one year after shipment.

 Proper disposal
Please dispose of this product as industrial waste (noncombustible).
Mercury parts and a nickel-cadmium battery are not used for this product.
 Warranty period
The warranty period of this product is for one year after supplying the appointed place.
 Operation
Be careful with the following cautions during use.
 Use the input within the rated range. Be careful since negligence of this caution may cause troubles of
the unit.
 There is a function to hold the maximum value and the minimum value with a measurement factor in this product.
A blackout is guaranteed and this value isn't also cleared by a power supply reset. However, the minimum value
may be updated in case input is not applied to a power up. For this reason, in order to make the past minimum
value hold by powering on, please apply input within 1 second after switching on a power supply.

1. Product outline
1.1 Usage of product
This single unit can measure and monitor maximum demand-current ×4, demand-current ×4, voltage ×6, current ×4,
maximum demand active power, demand active power, active-power, reactive-power, apparent power, power-factor,
frequency, watt-hour, var-hour, harmonic (voltage, current).
From a low tension circuit to a high tension circuit, it is adapted for various usages, such as a measurement
monitor of a power-receiving circuit, an energy conservation power monitor, a demand current measurement monitor,
and a harmonic monitor, a leakage monitor.
The intensive monitor united with the system is made in an addendum of analog output and a pulse output.
1.2 Features of product
 An input circuit can be selected by setting from 2VT,3CT and 3VT,3CT.
 Bar graph 1 measurement and digital 4 measurement are displayed simultaneously.
 Analog output 4 circuits and contact output 2 circuit can be taken out. (Option)
A contact output can be selected from a pulse output, an alarm output, and a CPU error output. (Please designate
it at an order.) And, output factor can be selected by setting.
 Two external operation inputs are possible. (Option) And, selection of reset input and a display change input is
possible at setting.
 Power supply is AC85‐264V，DC80‐143V (for both AC and DC uses).
 The mounting method of this unit is compatible with the mounting method of conventional 110 square mechanical meter.
This unit is mounted at 2 diagonal points.
 Integrated value of Wh and varh can indicate expansion to 3rd digit below the decimal point.
 Analog output is with a lower limit limiter.
 A tidal current measurement (output 2 quadrant) change is possible for var and cosφ.
 A backlight function is equipped. Selection of backlight-on, backlight-off, and auto backlight-off (Automatic
turning off the lights at the time of non-operation can be established), setting of brightness are possible.
LED：White
 The product with analog output can be selected from between analog output insulation type and the analog output
non-insulation type. (Please specify at the time of an order.)

This switch resets various alarms.
And, in the maximum and the minimum measurement
display, it is used as a switch that resets the
maximum and the minimum value.
In setting mode, it is used as a switch to which
a setting item is shifted.
Bar graph display
The measurement value of the main monitor
is indicated by the analog.
(Setting which does bar graph display
of the measurement value of sub-monitor
is also possible.)
Digital display

･Sub-monitor (Right)
･Sub-monitor (Center)
･Sub-monitor (Left)
SET
The switch from which integrated
value of the amount of electric
power is switched to normal display
(5 digits of integer) and expansion
indication (integer 2 digits ＋ below
decimal point, 3 digits) variously.
If it is not operated for 10 minutes after a
display change, it will usually return to a
display. It is used also as a switch which
changes to setting mode. If it continues
pushing 3 seconds or more, it will change to
setting mode.
In setting mode, it is used as a switch that
determines a set point.
RESET/
SHIFT

An upper limit (or lower limit) set point is
displayed.
Multiplying factor display
Unit display is automatically set in a
measurement range.
MODE
The switch to which general measurement display (usually) and
the harmonic measurement (voltage and current) display are changed.
In set mode, it is used as a switch that changes a setting item.
DISPLAY
This is a switch which changes the phase
(line) display of current (voltage).
If it is not operated for 10 minutes after a
display change, it returns to the original
phase (line) display. In setting mode, it is
used as a switch that terminates setting mode.
The switch to which measurement displays
