Introduction
Thank you for purchasing the HIOKI 9290-10 CLAMP ON ADAPTER.
To obtain maximum performance from the product, please read this
manual first, and keep it handy for future reference.
Overview
The Model 9290-10 is a clamp-on adapter rated for 1500A AC, with a
10:1 CT ratio.
In addition to the larger clamping capability, broad frequency character-
istics and good phase characteristics reliably provide clamp-on Power
HiTesters with expanded range and large current measurements.
Initial Inspection
When you receive the product, inspect it carefully to ensure that no
damage occurred during shipping. If damage is evident, or if it fails to
operate according to the specifications, contact your dealer or Hioki
representative.
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.
• If the product seems to be malfunctioning, contact your dealer or
Hioki representative. Pack the product carefully so that it will not be
damaged during shipment, and include a detailed written description
of the problem. Hioki cannot be responsible for damage that occurs
during shipment.
Follow these precautions to ensure safe operation and to obtain the
full benefits of the various functions.
Safety Symbol
The following symbols in this manual indicate the relative importance
of cautions and warnings.
Indicates that incorrect operation presents an extreme hazard
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.
Measurement categories
This product complies with CAT III safety requirements.To ensure safe opera-
tion of measurement products, IEC 61010 establishes safety standards for var-
ious electrical environments, categorized as CAT II to CAT IV, and called
measurement categories.
CAT II: Primary electrical circuits in
equipment connected to an AC
electrical outlet by a power cord
(portable tools, household appli-
ances, etc.)
CAT II covers directly measuring
electrical outlet receptacles.
CAT III: Primary electrical circuits
of heavy equipment (fixed installa-
tions) connected directly to the dis-
tribution panel, and feeders from
the distribution panel to outlets.
CAT IV: The circuit from the service drop to the service entrance, and to the
power meter and primary overcurrent protection device (distribution panel).
Using a measurement product in an environment designated with a higher-
numbered category than that for which the product is rated could result in a
severe accident, and must be carefully avoided.
Use of a measurement instrument that is not CAT-rated in CAT II to CAT IV
measurement applications could result in a severe accident, and must be care-
fully avoided.
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.
ent may be impossible in the presence of strong magnetic
transformers and high-current conductors, or in the pres-
g electromagnetic fields such as near radio transmitters.
Checks
product the first time, verify that it operates normally
no damage occurred during storage or shipping. If
damage, contact your dealer or Hioki representative.
rdg.:reading value (The value currently being measured and indicated on the
measuring product)
The clamp sensor and secondary coil are marked to indicate the direc-
tion of current flow, to ensure that the measurement current and out-
put current have the same phase.
Attach the clamp around only one conductor. Single-phase (2-wire) or
three-phase (3-wire) cables clamped together will not produce any reading.
The effect of conductor positioning of the clamp sensor clamped to the
secondary coil should be considered. Please verify the specifications
of the clamp sensor being used.
Safety
This product is designed to conform to IEC 61010 Safety Stan-
dards, and has been thoroughly tested for safety prior to ship-
ment. However, mishandling during use could result in injury or
death, as well as damage to the product. Be certain that you
understand the instructions and precautions in the manual
before use. We disclaim any responsibility for accidents or inju-
ries not resulting directly from product defects.

9290B980-05 13-09H
In the manual, the symbol indicates particularly important infor-
mation that the user should read before using the product.
The symbol printed on the product indicates that the user
should refer to a corresponding topic in the manual (marked with
the symbol) before using the relevant function.
Indicates a double-insulated device.
Indicates AC (Alternating Current).
Indicates that the instrument may be connected to or disconnected
from a live circuit.
Usage Notes
• To avoid short circuits and potentially life-threatening
hazards, never attach the product to a circuit that oper-
ates at more than the 600V.
• This product should only be connected to the sec-
ondary side of a breaker, so the breaker can prevent
an accident if a short circuit occurs. Connections
should never be made to the primary side of a
breaker, because unrestricted current flow could
cause a serious accident if a short circuit occurs.
• To avoid electric shock, do not touch the portion
beyond the protective barrier during use.
• To avoid electric shock, do not allow the product to get wet,
and do not use it when your hands are wet.
• To avoid electric shock when measuring live lines, wear
appropriate protective gear, such as insulated rubber gloves,
boots and a safety helmet.
• Note that the product may be damaged if current exceeding
the selected measurement range is applied for a long time.
store or use the product where it could be exposed to direct
temperature or humidity, or condensation. Under
