Safety Precaution■ Environment conditions
 Please be sure to use this product in a place that meets the following conditions. In places that do
not meet this condition, malfunctions and failures, and performance and product life may be reduced.
① Within the range of ambient temperature -10...55 ℃, humidity 5...90 ％ RH.
② Place free of corrosive gas. (Corrosive gas：SO2 / H2S, etc.)③ Place free of dust, salt and oily smoke.
④ Location that is not affected by vibration and shock.
⑤ Location that is not affected by external noise.
⑥ Altitude 2000m or less.
 If the input to this product is an inverter output such as cycle control, SCR phase angle control and
PWM control, measurement error may increase.

■ Outdoor use conditions.
① These products are not a dustproof, waterproof, and splash proof construction.
Please avoid the place with much dust. Please do not install in the place directly exposed to therain and water droplets. (IP code：IP30)② Please do not install in the place directly exposed to the sun even through the glass.
Discoloration and degradation of a name plate, and deformation of the box by the surface temperaturerise may cause.
③ Product life may shorten when the daily average temperature exceeds 40 ℃.

■ Mounting and wiring
Please refer to this instruction manual for installation and the wiring.
 Please refer to connection diagram for the wiring.
An improper connection may cause generation of high voltage on the CT secondary side, andwhich may lead to device malfunction, burning or fire.
 Hot line work is prohibited. There is a risk of explosion by electric shock, device
malfunction, burning, fire, or gas.
 Please use an electrical wire size suitable with the rated current.
Use unsuitable size electric wire, which may lead to a fire.
 Please check the tightening of the screw. If the screws are loose, it may cause a fire or
malfunction.
 The terminal cover is installed for preventing an electric shock accident.
Please close terminal cover after wiring work.

■ Preparation
This product must be set before use. Please read this manual and make the setting correctly.
If you make a mistake on the setting it does not operate correctly.

■ Maintenance and inspection① Inspection during energization is dangerous.
② No replacement in periodic inspection.
③ Please wipe off lightly with the dry soft cloth.
④ Please do not use the organic solvent, chemicals, cleaners, etc., such as an alcohol, for cleaning.

■ Storage
When storing this product for a long period, please keep it in a place that satisfies the following
environmental conditions.
 Within the range of ambient temperature (-20...70 ℃) and humidity (5...90 ％RH).
 Place where average daily temperature does not exceed 40 ℃.
 Locations with little dust, corrosive gases, salt and oil smoke.
 A place not subject to vibration or shock.

the trouble within the warranty period performs exchange or repair gratuitously.
However, if it corresponds to the next, it does not warrant.
① If it breaks down when converted or repaired except our company.
② If it breaks down by use out of specification range.
③ If the cause of trouble is based on cause other than this product.
④ Transportation, movement, damage by falling, and trouble.
⑤ Other, natural disasters, disasters, etc. In the case where the supplier side (Company and agent) is
not responsible.
This warranty is a guarantee for the delivered product. Cannot warrant the damage induced by trouble ofthis product.

■ Replacement cycle of the productWe recommend updating the product for 10 years as a rough standard.

■ Change of instruction manual written contents.
This instruction manual changes written contents without a notice by product improvement etc.

12 Troubleshooting
TroublePower LED is not lights
Display disappears
Does not switch to the setting
mode or test mode

Error in analog output

Probable cause
In the 13th and 14th terminals,
auxiliary power supply is not applied.
By auto off function, display is off
By the lock function of the test /configuration.

Setting of VT rating and CT rating iswrong
Output element setting is wrong
Range setting of each measurement
items is wrong
Setting of analog output is wrong(0...5V, 1...5V, 0...10V, 2...10V)
Wiring is wrong

Error in communication output

Error in active energy andreactive energy.
(Display, Communication, Pulse
output)Setting of VT rating and CT rating iswrong
Wiring is wrong
