DANGER
This product is designed to conform to IEC 61010 Safety Standards, and
has been thoroughly tested for safety prior to shipment. 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 injuries not resulting directly from product defects.
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.
In the manual, the symbol indicates particularly important
information that the user should read before using the
product.

Notes on Use
DANGER
To avoid short circuits and potentially life-threatening hazards,
never attach the clamp to a circuit that operates at more than the
600 Vrms, or over bare conductors.
Clamp-on probe should only be connected to the secondary 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.
WARNING
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.
Before measurement, check the position of the range switches.
The unit may be damaged it current at levels in excess of the
measurement limit is applied for a long time.
Current measurements exceeding 500 A, 1 kHz should be of short
duration. Heat builds up in the core proportionate to the current
value, and will reach a dangerous level over a long period of time.
CAUTION
Do not store or use the product where it could be exposed to direct
sunlight, high temperature or humidity, or condensation. Under such
conditions, the product may be damaged and insulation may
deteriorate so that it no longer meets specifications.
To avoid damage to the product, protect it from vibration or shock
during transport and handling, and be especially careful to avoid
dropping.
NOTE
Accurate measurement may be impossible in the presence of strong
magnetic fields, such as near transformers and high-current conductors,
or in the presence of strong electromagnetic fields such as near radio
transmitters.

Maintenance and Service
Thank you for purchasing the HIOKI "9010, 9010-10 CLAMP ON PROBE".
To obtain maximum performance from the product, please read this manual
first, and keep it handy for future reference.
The 9010, 9010-02, and 9010-10 are voltage output type clamp on probes,
which are applicable to 500A AC current measurements. The instrument can
be used to measure alternating current on a live power line without the need
to cut the wire. Easy operation and connection make them useful for
measuring alternating current and power in various fields.
Before using the product the first time, verify that it operates normally to
ensure that the no damage occurred during storage or shipping. If you find
any damage, contact your dealer or Hioki representative.
Before using the product the first time, verify that it operates normally to
ensure that the no damage occurred during storage or shipping. If you find
any damage, contact your dealer or Hioki representative.
Before using the product, make sure that the insulation on the test leads
and probes 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.
Overvoltage categories (CAT)
This product conforms to the safety requirements for CAT III measurement
products.
To ensure safe operation of measurement products, IEC 60664 establishes
safety standards for various electrical environments, categorized as CAT I to
CAT IV, and called overvoltage categories. These are defined as follows.
CAT I: Secondary electrical circuits connected to an AC electrical outlet
through a transformer or similar device.
CAT II: Primary electrical circuits in equipment connected to an AC electrical
outlet by a power cord (portable tools, household appliances, etc.)
CAT III: Primary electrical circuits of heavy equipment (fixed installations)
connected directly to the distribution 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).
Higher-numbered categories correspond to electrical environments with
greater momentary energy, so a measurement product designed for CAT III
environments can endure greater momentary energy than one designed for
CAT II. 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.
Safety symbols
This manual contains information and warnings essential for safe operation
of the product and for maintaining it in safe operating condition. Before using
the product, be sure to carefully read the following safety notes.
The following symbols in this manual indicate the relative importance of
cautions and warnings.
Follow these precautions to ensure safe operation and to obtain the full
benefits of the various functions.
When input to our recorder or tester, use 0.2 VAC range.
1. Connect the safety plug (banana plug, BNC connector) to the input
terminal. When using the BNC connector, align the BNC connector with
the connector guide notch on the current input connector. While pushing
the connector in, turn it to the right to lock it.
2. When input the unknown amount of measuring current, set the range to
the largest one (500 A).
3. Open the jaws and clamp the conductor.
4. Confirm whether the core tip connection part is closed certainly.
5. Set the proper range of the clamp on probe according to the measurement
value. Do not set the range from the measurement equipment (the
recorder etc.)
NOTE
Make sure that only one conductor is in the core. Single-phase (2-wire) and
three-phase (3-wire) lines clamped together will not produce reading.
Accuracy is guaranteed for 1 year at 23 5 (73 9 ) and 80%RH.
(Opening and Closing of the Sensor: Maximum 10000 times)
Cleaning the unit
To clean the product, wipe it gently with a soft cloth moistened with water or
mild detergent. Never use solvents such as benzene, alcohol, acetone, ether,
ketones, thinners or gasoline, as they can deform and discolor the case.
Service
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.
