Safety Notes

This device is designed to comply with 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 device. Using the device in a way not
described in this manual may negate the pro­vided safety features.
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
device defects.

This manual contains information and warnings
essential for safe operation of the device and for
maintaining it in safe operating condition. Before
using it, be sure to carefully read the following
safety precautions.

Safety Symbols

In the manual, the symbol indicates particu­larly important information that the user should
read before using the device.

The symbol printed on the device indicates
that the user should refer to a corresponding topic
in the manual (marked with the symbol) be­fore using the relevant function.

indicates a grounding terminal.
Indicates AC (Alternating Current).
Indicates the ON side of the power switch.
Indicates the OFF side of the power switch.

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 device

To ensure safe operation of measurement devices, 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 appliances, etc.)
CAT II covers directly measuring electrical outlet re­ceptacles.

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 en-

trance, and to the power meter and primary overcur­rent protection device (distribution panel).

Using a measurement device in an environment designated
with a higher-numbered category than that for which the de­vice 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 carefully avoided.

Operating Precautions

Before Use

Operating Precautions

Follow these precautions to ensure safe operation
and to obtain the full benefits of the various func­tions.

Before using the device for the first time, verify that
it operates normally to ensure that no damage
occurred during storage or shipping. If you find any
damage, contact your dealer or Hioki representa­tive.

Operating Precautions

6

Current Probe

• To avoid accidents, when using other mea­surement devices with this one, observe
the usage precautions described for each
device.

• When using a measurement instrument
that does not provide isolation between its
input terminals and chassis or other input
terminals, please pay attention to the fol­lowing points.
If a signal is applied to an input terminal
other than that to which the current probe
is connected, do not connect the ground­side terminal to any non-ground potential.
Otherwise, short-circuit current will flow
through the current probe or this device
from the ground terminal, which could
cause an electrical accident or damage.

To avoid electrical accidents and to maintain
the safety specifications of this device, con­nect the power cord only to a 3-contact (two­conductor + ground) outlet.

7

Operating Precautions

Observe the following to avoid damage to the
device.

• Installation and Operating Environment
Between 0 and 40°C (32 and 104°F); 80%RH or
less; indoors only.

• Do not store or use the device where it could be
exposed to direct sunlight, high temperature or
humidity, or condensation. Under such condi­tions, the device may be damaged and insula­tion may deteriorate so that it no longer meets
specifications.

• This device is not designed to be entirely water­or dust-proof. To avoid damage, do not use it in
a wet or dusty environment.

• To avoid damage to the device, protect it from
physical shock when transporting and handling.
Be especially careful to avoid physical shock
from dropping.

• To avoid damaging the power cord, grasp the
plug, not the cord, when unplugging it from the
power outlet.

Before turning the device on, make sure the
supply voltage matches that indicated on its
power connector. Connection to an improper
supply voltage may damage the device and
present an electrical hazard.

1. Turn the power switch off and connect the power

cord.
To avoid electrical accidents and to maintain the
safety specifications of this device, connect the
power cord only to a 3-contact (two-conductor +
ground) outlet.

2. Connect the power plug of the sensor to be used

to the power receptacle of the 3269.

3. Turn the 3269 power switch on, and check that the

front panel power indicator lights.

2.2 Measurement Procedure

See the 3273-50, 3273, 3274, 3275, 3276,
CT6700, or CT6701 instruction manual.
