Safety Information
Measurement categories
To ensure safe operation of measurement instruments, IEC 61010
establishes safety standards for various electrical environments,
categorized as CAT II to CAT IV, and called measurement
categories.
DANGER
•Using a measuring instrument in an environment
designated with a higher numbered category than
that for which the instrument is rated could result in
a severe accident, and must be carefully avoided.
•Using a measuring instrument without categories in
an environment designated with the CAT II to CAT
IV category could result in a severe accident, and
must be carefully avoided.
This instrument conforms to the safety requirements for CAT IV 600 V
measuring instruments.
CAT II: When directly measuring the electrical outlet receptacles of the
primary electrical circuits in equipment connected to an AC electrical
outlet by a power cord (portable tools, household appliances, etc.)
CAT III: When measuring the primary electrical circuits of heavy equipment
(xed installations) connected directly to the distribution panel, and
feeders from the distribution panel to outlets
CAT IV: When measuring the circuit from the service drop to the service
entrance, and to the power meter and primary overcurrent
protection device (distribution panel)

Operating Precautions
Operating Precautions
Follow these precautions to ensure safe operation and to obtain the
full benets of the various functions.
Ensure that your use of the product falls within the specications not
only of the instrument itself, but also of any accessories, options,
batteries, and other equipment being used.
WARNING
Do not use the instrument beyond its rated and
specicationranges.Doingsomayresultindamage
to the instrument or electric shock.
Before using the instrument, check the instrument for any damage
that may have been sustained while in storage or transit, inspect it,
and verify that it is operating properly. If you nd any faults, contact
your authorized Hioki distributor or reseller.
This instrument may cause interference if used in residential
areas. Such use must be avoided unless the user takes special
measures to reduce electromagnetic emissions to prevent
interference to the reception of radio and television broadcasts.

Operating Precautions
Installation
DANGER
Persons wearing electronic medical devices such as a
pacemaker should not use the Z5020 Magnetic Strap.
Such persons should avoid even proximity to the
Z5020 Magnetic Strap, as it may be dangerous. The
medical device's operation could be compromised,
posing risk to the wearer's life.
WARNING
Avoid the following locations that could cause an
accident or damage to the instrument.
•Exposed to direct sunlight or high temperature
•Exposed to corrosive or combustible gases
•Exposedtoastrongelectromagneticeldor
electrostatic charge
•Near induction heating systems (such as high-
frequency induction heating systems and IH
cooking equipment)
•Subject to vibration
•Exposed to water, oil, chemicals, or solvents
•Exposed to high humidity or condensation
•Exposed to high quantities of dust particles
Handling of the instrument
DANGER
To prevent electric shock, do not touch any areas
beyond the barrier while the instrument is in use.

9
Operating Precautions
CAUTION
To avoid damage to the instrument, protect it from physical
shock when transporting and handling. Be especially
careful to avoid physical shock from dropping.
After use, always turn OFF the power.
Handling of the cables
WARNING
To prevent electric shock, verify that the interior of the
cable is not exposed. If any color is visible from the
inside of the cable, do not use the instrument.
CAUTION
•Avoid stepping on or pinching cables, which could
damage the cables insulation.
•To prevent damage due to snapped wires, do not bend
or pull the base of the voltage sensor or cables.
The cable is hardened under the 0 degree or colder
environment. Do not bend or pull it to avoid tearing its
shield or cutting cable.
Precautions when transporting the instrument
CAUTION
During shipment of the instrument, handle it carefully so
that it is not damaged due to a vibration or shock.

10
Operating Precautions
Batteries
WARNING
Battery may explode if mistreated. Do not short
circuit,recharge,disassembleordisposeofinre.
To prevent instrument damage or electric shock, use
only the screws (M3 × 8 mm) for securing the battery
cover in place that are originally installed. If you have
lostanyscrewsorndthatanyscrewsaredamaged,
please contact your authorized Hioki distributor or
reseller for a replacement.
CAUTION
Heed the following instructions to avoid battery
performance drop or leakage.
•Do not mix old and new batteries, or different types of
batteries.
•Pay attention to the polarity markings “+–”, so that you
do not insert the batteries the wrong way around.
•Do not use batteries after their recommended expiry
dates.
•Do not leave a depleted battery inside the instrument.
• Replace batteries only with the specied type.
•Remove the batteries and store them if the instrument
will not be in use for a long time.
•Handle and dispose of batteries in accordance with local
regulations.
• ashes when the batteries are low. In this case, the
accuracy of the instrument is not guaranteed. Therefore, the
batteries should be replaced as soon as possible.

11
Operating Precautions
Handling the voltage sensor
IMPORTANT
If the measurement target is an insulated wire with dirt or moisture
on its insulation, the instrument may display lower values than
the actual voltage. If the surface of the measurement target’s
insulation has dirt or moisture on it, wipe it clean with a dry cloth
before measurement.

1Overview
1.1 Overview and Features
The PD3259 is a phase detector equipped with a voltmeter,
enabling it to be used to measure line voltages, check phase order,
measure frequency, and check for live wires and the ground phase
in 3-phase circuits.
By letting users check the state of 3-phase circuits at a glance, the
instrument delivers a high level of safety. In addition, because it lets
users measure line voltages, verify that wires are live, and check
phase voltages and the ground phase at once, it eliminates wiring
errors and reduces work times.
1 Overview
Phase detection function
The instrument detects normal
and reversed phase order for
3-phase circuits.
3-phase line voltage measurement
The instrument measures line voltages in
a 3-phase circuit from outside the wires’
insulation (without any metal contact).
Missing-phase prediction function
Frequency measurement
Hold function
The instrument holds the display
screen in the same state.
