The precaution for use.
1. Environment of usage and storage.
Don’t mount or store this product in the following environments. If the unit becomes defective due to the use
in an environment other than specified, it may be repaired for pay even during its warranty period (one year
after the date of delivery).
① Don’t mount or store the unit at a place where the ambient temperature is other than a range of -10～+55℃
or the relative humidity is higher than 85
% RH.
② Don’t mount or store the unit at a place where a corrosive gas such as SO 2 , H 2 S, etc. is generated.
Corrosive gas = Sulfur dioxide SO 2 / Hydrogen sulfide H 2 S / etc.
Large current bus / saturable reactor / etc.
③ Don’t mount or store the unit at a dusty place.
④ Don’t mount or store the unit at a place subjected to noticeable vibrations or shocks.
⑤ Don’t mount or store the unit at a place subjected to noticeable external noises.
⑥ 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.
2. Cautions on use in an outdoor panel
Be careful with the following items when using this unit in an outdoor panel.
① Don’t mount the unit at a place where it is directly exposed to rain or water drops, otherwise this unit may
become defective because of no water-proof or drip-proof structure.
② Don’t mount the unit at a dusty place.
③ Don’t mount the unit at a place exposed to direct sunlight. Avoid exposing the unit to direct sunlight even
through a glass window.
If the meter is directly exposed to sunlight, the surface temperature of the meter rises and the case may be
deformed if the temperature exceeds 80℃.
④ If the average temperature around the meter exceeds 40℃, the life of the unit may shorten.
3. 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 improves by doing the
power distribution of the auxiliary power and leaving it for about 2 hours.
4. Mounting and wiring
Mount and connect the unit by a technician while referring to the instruction manual and observing the following
cautions.
 Connect the unit after confirming the connection diagram. An improper connection may cause troubles
such as the generation of a high voltage on the secondary side of its current transformer or burning
of the unit or the occurrence of a fire.
 Don’t perform any connection in a hot line without turning off the power supply in advance, otherwise
an electric shock accident, troubles or burning of the unit, a fire, gas explosion, or other very
dangerous accidents may occur.
 The terminal cover is mounted for preventing an electric shock accident. Mount the terminal cover
without fail after the end of work.

5. Setting
This unit requires setting and confirmation of the measuring range, etc. before use. Wrong setting, if any, causes
malfunction of the unit. If setting should be wrong, neither measurement nor output becomes correct.
Carefully read the instruction manual before setting the unit.
■ Default setting
The default settings are as specified below at the delivery time. Set them according to the working conditions.
The input circuit of this product is the common use of 3-phase 3-wire (3φ3W), single-phase 2-wire (1φ2W), and
single-phase 3-wire (1φ3W). In case an input circuit is designated at the case of an order, it is shipped by
the default value of the designated input circuit. And, in case it does not do designation of the input circuit
(with no designation), it is shipped by the default value of 3-phase 3-wire (110V).
The unit will be delivered with your specified setting values, if so specified.

6. 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.
 The maximum value, a minimum value measurement factor
Measurement factor Maximum value measurement Minimum value measurement
Voltage ，Frequency ○ ○
 Be careful not to touch any terminal when power is applied to the unit.
 Don’t disassemble or modify this unit without any previous permission of our company, otherwise
the warranty does not apply to the unit any more. Also, modifications may cause troubles, a
fire, or other accidents. For specifications change, etc., please contact us.
7. Maintenance and check
① Wipe off the surface of the unit with a dry soft cloth. 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. Please keep in mind that it will break if a LCD is pushed strongly.
And, if a filter is pushed, a LCD face will touch a filter. Therefore, the pattern of the shape of a
circle or an ellipse may occur. Please do not push a filter strongly.
② Check the following items.
◎ Check the unit for damage in appearance.
◎ Check if indications conform to the inputs.
◎ Check if the unit is mounted normally without any loose connections of the terminal board after turning
off the power supply.
If a question has arisen or if the unit seems to be defective, please contact us.
