Safety Notes

Toensuresafe operation ofmeasurementdevices,IEC 61010
establishes safety standards for various electrical environ-
ments, categorized as CAT II to CAT IV, and called measure-
ment categories.
CAT II: Primary electrical circuits in equipment connected to
anACelectricaloutlet by a power cord (portabletools,
household appliances, etc.)
CAT II covers directly measuring electrical outlet re-
ceptacles.
CAT III:Primary electrical circuits of heavy equipment (fixed
installations) connected directly to the distribution
panel, and feeders from the distribution panel to out-
lets.
CAT IV:The circuit from the service drop to the service en-
trance, and to the power meter and primary overcur-
rent protection device (distribution panel).
Using a measurement device in an environment designated
with a higher-numbered category than that for which the de-
vice 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
Follow these precautions to ensure safe operation
and to obtain the full benefits of the various func-
tions.
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 representa-
tive.
Operating Precautions
Before Use

Operating Precautions
6
• To avoid accidents, when using other mea-
surement 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 fol-
lowing points.
If a signal is applied to an input terminal
other than that to which the current probe
is connected, do not connect the ground-
side 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.
Current Probe
To avoid electrical accidents and to maintain
the safety specifications of this device, con-
nect the power cord only to a 3-contact (two-
conductor + 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 condi-
tions, the device may be damaged and insula-
tion may deteriorate so that it no longer meets
specifications.
• This device is not designed to be entirely water-
or 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.

2.1 Preparations
• To avoid accidents, when using other mea-
surement 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 fol-
lowing points.
If a signal is applied to an input terminal
other than that to which the current probe
is connected, do not connect the ground-
side 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.

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