Safety

Safety Symbol

In the manual, the symbol indicates particularly important
information 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).

Wear appropriate protective insulation (insulating rubber gloves
and boots, helmet and etc.) when connecting and disconnecting
from live electric circuits.

The following symbols in this manual indicate the relative importance
of cautio ns and warnin gs.

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 hazard 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.

Usage Notes

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.

• To avoid short circuits and potentially life-threatening
hazards, never attach the product to a circuit that oper­ates at more than the 300 V, or over bare conductors.

• This product 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.

Preliminary Checks

Before using the product, make sure 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.

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.

Measurement Procedures

• Do not disconnect the output cable when the tester connected to
the clamp-on sensor is on or with the sens or clamped on a c onduc­tor to measure. This pre vents the 9695-0 2/03 main un it and sen sor
from malfunctioning.

• M3x5 screws and a spring washer assembly should be us ed for the
9695-02/03 terminal s. When using an other type of screw (e special­ly longer ones), be careful with the tightening torque. Tightening a
screw too much may damage the 9695-02/03.

Overview

The 9695-02/03 are voltage-output, clamp-on sensors used for 50 A
(9695-02) and 100 A (9695-03) rated AC measurement.
The 9695-02/03 sen sors are designed to measur e a lter nati ng currents
on a hot conductor without disconnecting it from the power line. Both
sensors are easy to operate and suitable for electric current and
power measurement in various fields.

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, alco­hol, 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 repre sentat ive. Pack t he prod uct ca refu lly so that it will not be
damaged during ship me nt, an d inc lu de a detailed written desc ription
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.

This product is designed to conform to IEC 61010 Safety Stan­dards, and has been thoroughly tested for safety prior to ship­ment. However , misha ndling during use could resul t 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 responsib ility for accid ent s or inju­ries not resulting directly from product defects.

Measurement categories (Overvoltage categories)

This product conforms to the safety requirements for CAT III measurement
products.
To ensure safe operation of measurement products, I
safety standards for various electrical environments, categorized as CAT I to
CAT IV, and called measurement 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.
Never use a CAT I measuring product in CAT II, III, or IV environments.
The measurement categories comply with the Overvoltage Categories of the
IEC60664 Standards.

EC 61010 establishes

• 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 sho ck when measuri ng live lines, wear app ro­priate protective gear, such as insulated rubber gloves, boots
and a safety helmet.

• Note that the product may be damaged if the applied current ex­ceeds the measurement range.

• Do not store or use the product w here it could be ex posed to dire ct
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.

• Be careful to avoid dropping the clamps or otherwise subjecting
them to mechanical s hock, whi ch could damage th e mating surfa c­es of the core and adversely affect measurement.

• Keep the clamp jaws and core slits free from foreign ob jects , which
could interfere with clamping action.

• Keep the clamp closed when not in use , to avoid accumulati ng dust
or dirt on the mating core surfaces, which could int erfere with clamp
performance.

• Do not fix the output terminal screws too tightly. The torque about

•m is recommended.

• Accurate measur ement may be impossible in the pre se nce of stro ng
magnetic fields, s uch as near transformers an d h igh -cu rrent co nd uc­tors, or in the presence of stro ng elec tromag netic fields s uch as near
radio transmitters.

• When connecting the cables to the output terminal, twist the cables
together as close to the termina l as poss ible to av oid the in fluenc e of
an external magnetic field

• Use the 9219 CONNECTION CABLE to connect this product to the
HIOKI clamp wattmeter. (The connector of the 9219 is a solderless
terminal to BNC.)

Attach the clamp around only one conductor. Single-phase (2-wire) or
three-phase (3-wir e) cabl es cla mped tog ethe r will no t produc e any re ading .
