This manual contains information and warnings
essential for safe operation of the instrument and
for maintaining it in safe operating condition.
Before using it, be sure to carefully read the follow-
ing safety precautions.
Safety Symbols
Safety Notes
This instrument is designed to comply with
IEC 61010 Safety Standards, 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 instrument. Be certain that
you understand the instructions and precau-
tions in the manual before use. We disclaim
any responsibility for accidents or injuries not
resulting directly from instrument defects.
In the manual, the symbol indicates particu-
larly important information that the user should
read before using the instrument.

Safety Notes
4
To ensure safe operation of measurement instruments, IEC
61010 establishes safety standards for various electrical envi-
ronments, categorized as CAT I to CAT IV, and called mea-
surement categories. These are defined as follows.
CAT I : Secondary electrical circuits connected to an AC elec-
trical outlet through a transformer or similar device.
CAT II : Primary electrical circuits in equipment connected to
anAC electricaloutletbya powercord(portabletools,
household appliances, etc.)
CAT III:Primary electrical circuits of heavy equipment (fixed in-
stallations) connected directly to the distribution pan-
el, 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 overcur-
rent protection device (distribution panel).
Higher-numbered categories correspond to electrical environ-
ments with greater momentary energy. So a measurement de-
vice designed for CAT III environments can endure greater
momentary energy than a device designed for CAT II.
Using a measurement instrument in an environment designat-
ed with a higher-numbered category than that for which the in-
strument is rated could result in a severe accident, and must
be carefully avoided.
Never use a CAT I measuring instrument in CAT II, III, or IV
environments.
The measurement categories comply with the Overvoltage
Categories of the IEC60664 Standards.

Operating Precautions
Follow these precautions to ensure safe operation
and to obtain the full benefits of the various func-
tions.
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 representa-
tive.
Operating Precautions
Before Use

Operating Precautions
6
• To avoid accidents, when using other mea-
surement instruments with this one,
observe the usage precautions described
for each instrument.
• To avoid electric shock or damage, when
connecting the clamp-on probe to a mea-
surement instrument that does not have its
input terminals isolated from the chassis,
or to an instrument that does not have it
input terminals isolated from one another
and signals are applied to other terminals,
do not connect the grounding terminal to
any point that is not at ground potential.
Otherwise, if the grounding terminal is con-
nected to a point that is not at ground
potential, a short circuit will occur.

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

7
Operating Precautions
Observe the following to avoid damage to the
instrument.
• 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 instrument where it
could be exposed to direct sunlight, high tem-
perature or humidity, or condensation. Under
such conditions, the instrument may be dam-
aged and insulation may deteriorate so that it no
longer meets specifications.
• This instrument 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 instrument, protect it
from physical shock when transporting and han-
dling. 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.

1. Turn the power switch off and connect the power
cord.
To ensure safety, connect the power cord to a
properly grounded outlet (2-contacts + ground).
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, or 3276
instruction manual.
Before turning the instrument on, make sure
the supply voltage matches that indicated on
the its power connector. Connection to an
improper supply voltage may damage the
instrument and present an electrical hazard.

4. Replace the fuse holder by reinserting it into the
power input socket.
• To clean the instrument, 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 damage is suspected, contacting your dealer
or Hioki representative.
• When sending the instrument for repair, pack
carefully to prevent damage in transit. Include
cushioning material so the instrument cannot
move within the package. Be sure to include
details of the problem. Hioki cannot be responsi-
ble for damage that occurs during shipment.
