damage occurred during shipping. If damage is evident, or if it fails to
operate according to the specifications, contact your dealer or Hioki
representative.
Preliminary Checks
• Before using the product the first time, verify that it operates nor-
mally to ensure that the no damage occurred during storage or ship-
ping. If you find any damage, contact your dealer or Hioki
representative.
• Before using the product, make sure that the insulation on the
cables and the protective tube of the fuse holder is undamaged and
that no bare conductors are improperly exposed. Using the product
in such conditions could cause an electric shock, so contact your
dealer or Hioki representative for repair.
Maintenance and Service
• To clean the product, wipe it gently with a soft cloth moistened with
water or mild detergent. Never use solvents such as benzene, alco-
hol, acetone, ether, ketones, thinners or gasoline, as they can
deform and discolor the case.
• To verify that the product operates normally,connect the tester to a
three-phase power supply that has a collect phase order and make
sure that the indicator dial rotates in the direction of the arrow.
• If the product seems to be malfunctioning, your dealer or Hioki rep-
resentative. Pack the product carefully so that it will not be damaged

Safety Symbol
The following symbols in this manual indicate the relative importance
of cautions and warnings.
Indicates that incorrect operation presents an extreme haz-
ard that could result in serious injury or death to the user.
Indicates that incorrect operation presents a significant haz-
ard that could result in serious injury or death to the user.
Indicates that incorrect operation presents a possibility of
injury to the user or damage to the product
Advisory items related to performance or correct operation of
the product.
This manual contains information and warnings essential for safe
operation of the product and for maintaining it in safe operating condi-
tion. Before using the product, be sure to carefully read the following
safety notes.
• Continuous use for long periods of time may be dangerous. Be sure
to use the tester within the maximum permissible use times given
above.
• If the power voltage is unknown, be sure to check it first with a volt-
meter before connection the tester.
• This tester is designed to be used in the horizontal position (±15
°
).
Using it in other attitudes may prevent the dial from rotating, and
cause faulty readings.
The ABS case and all movable components are resistant to vibration
and impact, providing the strength needed for field application. And its
compact size and light weight provides superior portability. In addition,
the leads are color-coded to match the dial, making it easy to tell R, S
and T leads from each other.
Connect the tester to a three-phase circuit. If the circular dial rotates in
the direction of the arrow, the phase connection order is RST.
1. Open the fuse holder by turning one end counterclockwise.
2. Replace the fuse inside the fuse holder.
3. Close the fuse holder by pushing the ends back together, then turn-
ing one end clockwise.

Advisory items related to performance or correct operation of
the product.
This manual contains information and warnings essential for safe
operation of the product and for maintaining it in safe operating condi-
tion. Before using the product, be sure to carefully read the following
safety notes.
• Continuous use for long periods of time may be dangerous. Be sure
to use the tester within the maximum permissible use times given
above.
• If the power voltage is unknown, be sure to check it first with a volt-
meter before connection the tester.
• This tester is designed to be used in the horizontal position (±15
°
).
Using it in other attitudes may prevent the dial from rotating, and
cause faulty readings.
The ABS case and all movable components are resistant to vibration
and impact, providing the strength needed for field application. And its
compact size and light weight provides superior portability. In addition,
the leads are color-coded to match the dial, making it easy to tell R, S
and T leads from each other.
Connect the tester to a three-phase circuit. If the circular dial rotates in
the direction of the arrow, the phase connection order is RST.
1. Open the fuse holder by turning one end counterclockwise.
2. Replace the fuse inside the fuse holder.
3. Close the fuse holder by pushing the ends back together, then turn-
ing one end clockwise.
