Introduction
Thank you for purchasing the HIOKI 9695-02/03 CLAMP ON SEN-
SOR. To obtain maximum performance from the product, please read
this manual first, and keep it handy for future reference.
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 sensors are designed to measure alternating 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, 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

Safety
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 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.
Measurement categories
This product conforms to the safety requirements for CAT III measurement
products.
To ensure safe operation of measurement products, IEC 61010 establishes
safety standards for various 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 cir-
cuits 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).
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.
Safety Symbol
Indicates cautions and hazards. When the symbol is printed on the
instrument refer to a corresponding topic in the Instruction Manual.
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 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 hazard
that could result in serious injury or death to the user.

Usage Notes
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.
• To avoid short circuits and potentially life-threatening
hazards, never attach the product to a circuit that oper-
ates at more than the 300 V, or over bare conductors.
• 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 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 the applied current ex-
ceeds the measurement range.
• 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.
• Be careful to avoid dropping the clamps or otherwise subjecting
them to mechanical shock, which could damage the mating surfac-
es of the core and adversely affect measurement.
• Keep the jaw free from foreign objects, which could interfere with
clamping action.
• Keep the jaw closed when not in use, to avoid accumulating dust
or dirt on the mating jaw, which could interfere with clamp perfor-
mance.
• Do not fix the output terminal screws too tightly. The torque about
•
0.5N m is recommended.
• Accurate measurement may be impossible in the presence of strong
magnetic fields, such as near transformers and high-current conduc-
tors, or in the presence of strong electromagnetic fields such as near
radio transmitters.
• When connecting the cables to the output terminal, twist the cables
together as close to the terminal as possible to avoid the influence 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.)
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 sensor clamped on a conduc-
tor to measure. This prevents the 9695-02/03 main unit and sensor
from malfunctioning.
• M3x5 screws and a spring washer assembly should be used for the
9695-02/03 terminals. When using another type of screw (especial-
ly longer ones), be careful with the tightening torque. Tightening a
screw too much may damage the 9695-02/03.
Attach the clamp around only one conductor. Single-phase (2-wire) or
three-phase (3-wire) cables clamped together will not produce any reading.
