Introduction

Thank you for purchasin g th e HIO KI “9694 CLAMP ON SENSOR”. To
obtain maximum perfo rm ance from the prod uc t, plea se read this man­ual first, and keep it handy for future reference.

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.

Preliminary ChecksM

• Before using the product the first time, verify that it operates nor­mally to ensure tha t th e n o d am age oc curred 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
cables is undamaged and that no bare conductors are improperly
exposed. Using the product in such con di tion s co uld 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, 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 representative.

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
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.

Measurement categories (Overvoltage categories)

This product complies with CATIII safety requirements.
To ensure safe operation of measurement iproducts, IEC 61010 establishes
safety standards for various electrical environments, categorized as CAT I to
CAT IV, and called measurement categories. These are defined as follows.

: Secondary electrical

CAT I
circuits connected to an AC
electrical outlet through a
transformer or similar device.

:Primary electrical cir-

CAT II
cuits in equipment connected
to an AC electrical outlet by a
power cord (portable tools,
household appliances, etc.)

: Primary electrical cir-

CAT III
cuits of heavy equipment
(fixed installations) connected directly to the distribution panel, and feeders
from the distribution panel to outlets.

: The circuit from the service drop to the service entrance, and to the

CAT IV
power meter and primary overcurrent protection device (distribution panel).
Higher-numbered categories correspond to electrical environments with
greater momentary energy. So a measurement device designed for CAT III
environments can endure greater momentary energy than a device designed
for CAT II.
Using a measurement product in an environment designated with a higher­numbered category than that for which the pr oduct 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.

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).

Indicates that the instrument may be connected to or disconnected
from a live circuit.

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.

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 AC.

• 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.

• 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 curren t exceeding the se­lected measurement range is applied for a long time.

• Do not store or us e the p roduct where it co uld be expos ed to d irect
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 product 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 c ore slit s free from forei gn obje cts, whic h
could interfere with clamping action.

• Keep the clamp c losed wh en not in u se, to avo id accumul ating dust
or dirt on the mating core surfaces, which could int erfere with clamp
performance.

• Avoid stepping on or pinching the cable, which could damage the
cable insulation.

• To avoid damaging the cables, do not bend or pull the cables.

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.

Measurement Procedures

• When disconnecting the BNC connector, be sure to release the
lock before pulli ng o f f t he c on nec tor. Forcibly pulling the con nec to r
without releasing th e lo ck , or p ulling on the cable, ca n d am age the
connector.

• To prevent damage to the connected instruments, never connect
or disconnect a sensor while the power is on.

Attach the clamp around only one conductor. Single-phase (2-wire) or
three-phase (3-wire) cables clamped together will not produce any
reading.
