with a higher-numbered category than that for which the instrument is rated could result in a severe accident, and must be
ca
refully avoided.
• Using a measuring instrument without cate
ment designated with the CAT II to CAT IV category could result
in a severe accident, and must be carefully avoided.

Operating Precautions
Handling the Instrument
To avoid damage to the instrument, protect it from physical shock when
transporting and handling. Be especially careful to avoid physical shock
from dropping.
This instrument and Model PW9020 Safety Voltage Sensor may cause
interference if used in residential areas. Such use must be avoided
Reference
Handling the Voltage Sensor
unless the user takes special measures to reduce electromagnetic
emissions to prevent interference to the reception of radio and television broadcasts.
T ouching any of the high-voltage points inside the PW9020 Safety
Voltage Sensor is very dangerous.
Customers are not allowed

Doing so may cause fire, electric
to modify, disassemble, or repair the
shock, or injury.
IMPORTANT
• The instrument may not be able to accurately measure waveforms
that contain components outside the frequency range indicated in
the "Effective measuring range" (p.187) section of the specifications
(45 Hz to 66 Hz).
• If the measurement target is an insulated wire with dirt or moisture
on it
s insulation, the instrument may display lower values than the
actual voltage and power. If the surface of the measurement target’s
insulation has dirt or moisture on it, wipe it clean with a dry cloth
before measurement.
Handling the Clamp Sensor
• Be careful to avoid dropping the clamp sensor or otherwise subjecting
them to mechanical shock, which could damage the mating surfaces
and adversely affect measurement.
• Keep the clamp jaws and core slits free
could interfere with clamping action.
• Keep the clamp closed when not in use, to avoid accumulating dust or
dirt on the facing core surfaces, which could interfere with clamp performance.
Handling the Cords
To prevent cord damage, do not step on cords or pinch them between
other objects. Do not bend or pull on cords at their base.
Handling the Battery Pack
• To avoid the possibility of explosion, do not short circuit, disassemble or incinerate battery pack. Handle and dispose of batteries in accordance with local regulations.

• For battery operation, use only the HIOKI Model PW9002 Battery
Set. We do not take any responsibility for accidents or damage
related to the use of any other batteries and/or screws.

Operating Precautions
• Do not use the screw holes used for installing the protector or the battery
case for other purposes. Doing so may damage the product.
• Avoid using an uninterruptible power supply (UPS) or DC/AC inverter

instrument. Doing so may damage the instrument.
• Install the battery case onto the PW3365 using the screws supplied
with the PW9002 (M3 x 25 mm), keeping the protector attached to the
case. Installing the battery case with the protector removed or using
screws longer than the accompanying screws may damage the
PW3365.
• Observe the following to avoid damage to the instrument.
•Use the battery pack in an ambient temperature range of 0°C to 40°C
and charge it in an ambient temperature range of 10°C to 40°C.
•If the battery pack fails to finish charging within the stipulated time,
disconnect the AC adapter to stop charging and contact your dealer
or Hioki representative.
•Consult your dealer or nearest service station should liquid leaks,
strange odor, heat, discoloration, deformation and other abnormal
conditions occur during use, charging or storage. Should these conditions occur during use or charging, turn off and disconnect the
instrument immediately.
Reference
• The battery pack is a consumable. If you are able to use the instrument for only a limited period of time despite the battery pack being
prope
rly charged, the battery pack’s service life is at an end, and it
should be replaced.
• When a battery pack that has not been used for a long time is used,

Guidance on measurement procedures
The instrument provides guidance on configuring basic settings, connecting the instrument to
the measurement target, configuring recording
settings, and starting measurement, allowing
even users who have never used a power meter
before to easily set up the device and perform
measurement.
See: Quick Set function (p.127),
Measurement guide (provided separately)
Ability to perform demand measurement
In addition to basic measurement of parameters
such as voltage, current, power, power factor,
and energy , the instrument can perform demand
measurement, an important task in power management.
See: "5.7 Viewing a Demand Graph" (p.106)
Demand graph
Ideal for power measurement of commercial frequencies
Since the instrument can automate data collection and measurement
over extended periods of time thanks to its SD memory card, USB interface, and LAN interface, it is ideal for power measurement of commercial frequencies in applications such as building and factory power
maintenance and management.

1.1 Product Overview
Overview Chapter 1
1.1 Product Overview
The PW3365 Clamp on Power Logger is a clamp-type power meter capable of
measuring lines with from single-phase to three-phase four-wire.
Dedicated voltage sensors can be used to safely

1.2 Features
1.2 Features
Ability to perform measurement safely using metal contactless
voltage sensors
The PW9020 Voltage Sensor can be used to measure voltage from insulated wires.
Since no contact is made with metal parts, measurement can be performed safely.
The PW9020 features a safe design that is compatible with CAT IV (300 V) and CAT
III (600 V) use.
Quick Set function
Simply follow guidance provided by the instrument to set up and operate the instrument by configuring basic settings, connecting the instrument to the measurement
t
arget, configuring recording settings, and starting measurement.
See: "Chapter 7 Quick Set" (p.127), Measurement guide (published separately in
color)
Wiring Check (wiring confirmation)
If the instrument has been connected improperly, tips for connecting it properly will
be shown.
See: "3.9 Verifying Correct Wiring (Wiring Check)" (p.65)
Ability to operate for about 5 hours on battery power
Even when AC power is unavailable, the optional battery pack can be used to enab le
about five hours of measurement.
See: " Installing (replacing) the Battery Pack" (p.32)
Corresponding to the various power line
The instrument can perform single-phase/2-wire (up to three circuits), single-phase/
3-wire, 3-phase/3-wire (2-power measurement/3-power measurement), and 3phase/4-wire measurement. When performing single-phase/3-wire, or 3-phase/3wire 2-power measurement, the instrument can perform power and leakage current
measurement simultaneously.
See: "4.2 Changing Measurement Settings" (p.72)
Broad operating temperature range
The instrument can be used at temperatures ranging from 0°C to 50°C. However,
the operating temperature range is limited to 0°C to 40°C when operating on battery
power.
TFT color LCD
The instrument uses an LCD that is easy to see in both dim and bright conditions.
