Warranty
Warranty malfunctions occurring under conditions of normal use in
conformity with the Instruction Manual and Product Precautionary
Markings will be repaired free of charge. This warranty is valid for a
period of three (3) years from the date of purchase. Please contact
the distributor from which you purchased the product for further information on warranty provisions.
Introduction
Thank you for choosing the Hioki P9000-01, P9000-02 Dierential
Probe. Preserve this manual carefully and keep it handy to make full
use of this product for along time.
Overview
The product is a dierential probe that is connected to a Memory
HiCorder input unit. The probe divides two high voltages input to its
high and low terminals by 100 or 1000 and then outputs the dierence as a signal relative to ground. The P9000-02 includes AC RMS
value output functionality.
Power can be supplied via the optional AC adapter or a commercially available USB cable.
Verifying Package Contents
When you open the package, carefully inspect the product to ensure
that everything is in good condition, and that no damage occurred
during shipping. Carefully check the accessories and connectors.
If the product seems to have been damaged or does not work as
specied, contact your authorized Hioki distributor or reseller.
Cleaning
If the product becomes dirty, slightly moisten a soft cloth moistened
with water or a neutral detergent and wipe the product clean.
IMPORTANT
Never use solvents such as benzene, alcohol, acetone, ether,
ketones, thinners or gasoline, as they can deform and discolor the
case.
Repair
If the product seems to be malfunctioning, conrm that the AC adapter and the USB cable are connected properly before contacting your
authorized Hioki distributor or reseller.
WARNING
Touching any of the high-voltage points inside the
product is very dangerous. Do not attempt to modify, disassemble, or try to repair the product. Doing
so may cause a re, electric shock, or injury.
Calibration
IMPORTANT
Periodic calibration is necessary in order to ensure that the in-
strument provides correct measurement results of the specied
accuracy.
The calibration period varies with the conditions and environment of
use. It is recommended to determine a calibration period based on
those factors and to have the product regularly calibrated by Hioki.
Please contact your Hioki distributor to have your product periodically calibrated.
Precautions during shipment

• Attach a description of the issue when sending out your product for
repair.
Disposal
Dispose of the product in accordance with local regulations.
Safety Notes
This product is designed to conform to IEC 61010 Safety Standards,
and has been thoroughly tested for safety prior to shipment. However, using the product in a way not described in this manual may

Carefully read the following safety notes before using the product.
WARNING
Mishandling product could result in bodily injury or
even death, as well as damage to the product. Familiarize yourself with the instructions and precautions in this manual before using the product.
WARNING
• Protective Gear
Performing measurement using this product involves live-line work. To prevent an electric shock,
use appropriate protective insulation and adhere
to applicable laws and regulations.
• Electricity can potentially cause serious events
such as an electric shock, heat generation, re,
and an arc ash due to a short-circuit. If you have
not used electrical measuring instrument before,
you should be supervised by a technician who
has experience in electrical measurement.

Measurement categories
To ensure safe operation of measuring instruments, IEC 61010
establishes safety standards for various electrical environments, cat-
egorized as CAT II to CAT IV, and called measurement categories.
WARNING
• Using a measuring product in an environment
designated with a higher-numbered category than
that for which the product is rated could result in
a severe accident, and must be carefully avoided.
• Never use a measuring product that lacks cat-
egory labeling in a CAT II to CAT IV measurement
environment. Doing so could result in a serious
accident.
This product conforms to the safety requirements for CAT III 1000 V,
CAT IV 600 V measuring instruments.
CAT II: When directly measuring the electrical outlet recep-
tacles 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)

Usage Notes
Observe the following precautionary information to ensure that the
product can be used safely and in a manner that allows it to perform
as described in its specications.
WARNING
To prevent an electric shock, conrm that the white
or red portion (insulation layer) inside the cable is
not exposed. If a color inside the cable is exposed,
do not use the cable.
WARNING
Do not allow the product to get wet, and do not take
measurements with wet hands. This may cause an
electric shock.
CAUTION
• To avoid damage to the product, avoid subjecting it to
vibration or mechanical shock during transportation
and handling. Exercise particular care to avoid subjecting the product to mechanical shock, for example
by dropping.
• Do not store or use the product where it could be exposed to direct sunlight, high temperatures or humidity, or condensation. Under such conditions, the product may be damaged and insulation may deteriorate
so that it no longer meets specications.
• This product is not designed to be entirely waterproof
or dustproof. Do not use it in an especially dusty environment, nor where it might be splashed with liquid.
This may cause damage.
This product complies with EN 61326 Class A.
This product 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.

Measurement Method
WARNING
• For your safe operation, do not connect the prod-
uct to the primary of the distribution panel.
• Do not connect the product to a voltage or current
that exceeds the rating indicated on the product
labeling or the measurement range indicated in its
specications. Doing so may damage the product
or cause it to become hot, resulting in electric
shock or bodily injury.
• To avoid short circuits and electric shock, do not
short-circuit two wires to be measured by bringing the metal part of the test lead into contact with
them. Never touch the metal end.
WARNING
When supplying power through the USB-micro B
jack, make sure that the USB ground pin of the
power source is connected to the ground. Using an
ungrounded USB terminal could cause an electric
shock.
CAUTION
To prevent damage to the connector, be sure to release
the locking mechanism, grip the head of the connector
(not the cord), and pull it out.
